Requests to https://api.amplitude.com/ being blocked by CORS policy

Hello!We’ve recently come across an issue with missing event data from a large group of our users.One of our users agreed to record a HAR file of their browser session for us to investigate and it shows that requests to Amplitude are being blocked by CORS policy. Here is a bunch of requests to Amplitude from the user’s browser session log, all - without a response from the server. The encountered error, according to the user’s Console log, is: Access to XMLHttpRequest at 'https://api.amplitude.com/' from origin 'https://lm.rt.ru' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.api.amplitude.com/:1 Failed to load resource: net::ERR_FAILED The user is using desktop Chrome 93.0.4577.82 browser on Microsoft Windows 10.0 and a VPN tool to connect to our resource. We were not able to reproduce the same error with the missing Access-Control-Allow-Origin header under similar surroundings (OS, browser and VPN tool).

Events not showing up in Amplitude (looks like some events are lost)

Hello! I’ve implemented an integration with Amplutude via a js SDK. I’m able to see all my events, however some events are not showing up in Amplutude itself, despite showing in debugger and in Network tab of the browser.For example: Here are a screenshot of a debugger. All events have the same Session Id equal 1637612692926. I’m also able to see events being sent in a network tab of the browser.However, in Amplitude dashboard I can only see so many events: Looks live event recording broke after E_LOGIN_ATTEMPT.What can I do to fix it? Thanks in advance!

Importing non-events disguised as events from Snowflake causes error.

If the title makes you scratch your head, fear not, I scratched mine so much it hurts. Also, I am as new as it gets to Amplitude, so I might be missing something really basic. All our marketing spend, coming from a dozen or so partners is stored in Snowflake, where it is also harmonised to our in-house tracking setup. It is not event-like by nature, but I was asked to try to bring it to Amplitude nonetheless, so I tried to make it appear as event-like as possible.Below my attempt, as simple as pretending all our costs pertain to one user, mr. string-zero. CREATE OR REPLACE VIEW a_db.a_schema.a_view_exposed_to_amplitudeAS SELECT '0' AS user_id, to_timestamp_ntz(a_date_field) AS ts, date_part(epoch_millisecond, a_date_field::timestamp) AS epoch, 'costs_per_cid' AS event_type, object_construct('cid', cost_token, 'clicks',clicks, 'usd_costs', costs, 'impressions', impressions) AS event_properties, object_construct() AS user_propertiesFROM a_db.a_schema.a_cost_table;All went we

Why my events get disappeared

Hi, I posted some new events through HTTP API 2 days ago and made some charts for these events like this. It works fine, but when I look at the dashboard today, all the events I posted 2 days ago count become 0 in the charts and I also can’t find them in user stream. However, I can still see them in data (All the events started with ‘first’).Does anyone know about this issue? Since I made dashboards for these events, I can make sure that these events are posted successfully.

Reduced eps reason with 'Too many devices with the same user ID.'

HelloWe’ve recently started to trial Amplitude in our latest iOS release. We have four projects setup as environments and on a daily basis we’re looking at our Development environment as we build out our features which has been working well. From today, I’ve been unable to review any events on our User Look-Up after refreshing, logging out and clearing all of my chrome cache and logging back in. I’ve also tried this on Safari. I’ve worked out from looking into the Chrome Debugger Network view that I’ve exceeded the a quota.{"reduced_eps_reason":" Too many devices with the same user ID.","code":429,"exceeded_daily_quota_users":{},"throttled_events":[0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29],"throttled_users":{"kelvin.harron@vyprco.com":2},"error":"Too many requests for some devices and users","eps_threshold":2}I have two questions.How do I prevent this from happening? Can I clear out this user and reset the data? I log into different devices and si

A user property is not removed/updated on an event when a null or undefined value is passed in, why is this?

Hi, I wanted to clarify some behavior I’m seeing in our Amplitude events.I’m looking at a user’s event stream and see that for their events they have a user property, let’s just say it’s called name and it has a value of “Chris”.  Then I use the Amplitude SDK to log another event, something like thisamplitudeClient.logEvent('Changed name', {user_properties: { 'name': undefined }}); I notice that in this event, the user property will still show up as “Chris” instead of being nullified or removed. I was wondering why this is the case and how to remove user properties if they are undefined/null. Would I need to use the Identify API to explicitly remove the property?

Google Tag Manager Amplitude Tag Template

Hey Everyone:I would love to hear any lesson’s learned or “aha” moments they have experienced with the Google Tag Manager Tag Template. Please feel free to add them to this convo to help others going through this migration of GA Tags to the Amplitude Tag Template😁Here is my Aha:My “aha” was flexibility to create my own Custom Marketing Interaction events where an event is fired anytime a URL with UTMS was loaded. This would allow me to help metric marketing touch-points and understand how customers are coming to my site beyond standard traffic reporting.-Robbie

Is it OK to include project API key in open source project?

Dear Amplitude friends, I have an open-source project, and I want to track usage. Is it OK to include(hard-code) my project API key in this open-source project? Is such action going to violate the license of Amplitude? Are they any other legal concerns preventing me from doing that? Please consider the extreme case that when hackers acquire my open-source project, there might be excessive pings into Amplitude’s system using my project API key with ill intentions and without my supervision. Does Amplitude have concerns over that? Do you know if there are precautions or recommendations you can help suggest? Best regards,-Chance A

Missing/corrupt user property

Our company has using Data/Analytics with our web app for several months. We have a custom user property 'organisationId', however last week we noticed it has been removed from our tracking plan without any action taken on our part. It does not appear in the list of user properties in the tracking plan, and is not being recorded in user events, despite the property still being posted by the client.​​​​​Example of organisationId being sent by the client (inspected with the Amplitude chrome extension on a production environment)  If I try to recreate the user property, I receive the message "Unable to save property. Unable to add property organisationId because it already exists. The activity log will also not load so I cannot check to see if there were any changes I'm unaware of. How can I restore the user property? Can we restore the property on all the events that have been logged in the interim?

Help setting up Amplitude tag / template to map GA4 events!

Hi community!I’ve tried to do this by myself, but I’m failing miserably. So, first of all, if I install a simple javascript tag for Amplitude in GTM, I’m able to generate and get my events with my API key and everything. So, I generally know how to do things.But here, I’m struggling with the Amplitude tag from the Amplitude Template available in the Google Tag Manager library: I’m setting up everything with my api key, my Amplitude tag is firing but nothing is getting sent to Amplitude.I’ve set up as a trigger my GA4 events, and I have set up the Amplitude tag type to “track”, and under there I’ve set up the Event Type value to {{Event}} so that I get the name of my GA4 event (I’ve checked in my data layer variable, the Event variable is set correctly). But my Amplitude is receiving NO data when I’m doing this :(What am I missing?

How do we set session in Amplitude while using Segment in Cloud Mode?

 How do we set session in Amplitude while using Segment in Cloud Mode?There are 2 ways to sessionize your data in Amplitude if you are using Segment cloud mode.    Amplitude’s Best Practices: The first method is where we are passed in sessionId into the integrations object.Sample code:1 2 3 4 5 6 7 8 9 analytics.track({ userId: 'samplitude1234' event: 'subscription renewed', integrations: { 'Amplitude': { 'session_id': 1531845205000 // Start time of session in milliseconds since epoch } } }); The second option is to send your own custom session property, which would be a regular property in your track calls: 1 2 3 4 5 analytics.track('Gold Payment Option Clicked', { payment type: 'credit card', membership type: 'individual', grx_session_id: 'eda546f4-9ea6-4d40-a3b2-54491ac7a18a' });Either option works for Amplitude.It is more so dependent on which one makes most sense for your team from a technical standpoint. The first option requires customizing Segment's integrations object and also

User IP and country is inconsistent

Hi, guys!This question is for amplitude integration. We made the following changes at same time：1.Change Amplitude SDK to Segment SDK2.Change Amplitude(Actions) to Amplitude cloud-mode Found the following problems;Inconsistent userip before and after. This is by no means a single event, Nearly half of the user ip changed.This leads to a change in the user’s country information. For example：(Changes started on November 5)ip:   before is “115.164.42.244” / after is ”10.85.199.68”country: before is “Malaysia” / after is “United Kingdom” I want to know the following answer：1.Is the country different due to ip?2.How to get ip(Amplitude SDK / Segment SDK)?3.Is this caused by the SDK?4.Do i have a way to solve this problem？

Cannot read file in Python from Export API due to decoding issue

 Greetings, You can see a block of code to get the data from EXPORT API via Python, above. Response’s status code is “200”.I want to open the file in Python to use it via Pandas and make some manipulations. However, I cannot read it. I have used the code below but it created a file in my Desktop: z = zipfile.ZipFile(io.BytesIO(res.content))z.extractall() I simply used the pd.read_json() as in below:pd.read_json(z.open(f'{z.namelist()[-1]}')) But it returned an error below:UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 1: invalid start byte How can I solve this problem?

Clean user property

If I update a user property value to null on segment identify, Amplitude doesn't change user property value and it shows previous value. It seems to be an issue on Amplitude’s API side. What can I do to clean/empty value??

How does "offset" work?

I have a funnel of “Contacted” to “Replied” leads for past 30 days, which should show me conversion rate. Though I need exclude “contacted” events which were last 7 days and include those happened 37-30 days ago, but I want see all “replied” event during last 30 days. I apply Offset when choosing data period (last 30 days + Offset 7 days). But I don’t see the right numbers. Can anyone explain in details how “offset” changes my funnel?

Is it possible to track utm parameters for mobile apps?

Is it possible to track the utm parameters from app deeplinks in Amplitude?We are rolling out share functionality (e.g. the deeplink might be “app.myapp.com/sleep_program?utm_source=app_share_button”) and we want to track usage of the new feature. So ideally something like a count of the number of people who come to the app via ‘app_share_button’. We’re using the React Native SDK fyi.
