Over the last day, I got 55.2k failed events not sent to Intercom due to Destination Throttling, Internal Errors and Invalid Requests. Specifically Throttling and Internal errors nature is not clear to me. What should I do to fix these issues and pass data without such failures?
In addition, the user attributes from Amplitude I've selected to send to Intercom don't appear there. The events are recorded fine (with the exception of issues I listed above). What is the reason? Will the attributes get created automatically similar to events, or do I need to manually create the custom attributes I expect to receive on Intercom first?
