I need a way to be able to tell the difference in Amplitude between when an event property’s value is an empty array/list “” vs. when the event did not receive a value for that event property at all.
Doing the usual = (none) or set is (none) doesn’t work at telling them apart. I think I can use the glob match function but I’m struggling to figure out what the correct syntax would be since the square brackets are used as part of the glob match language. How do I escape them and write a glob match string that resolves to ?
Basically, can I create a chart that can capture the difference between the events in the 2 screenshots below (specifically for the user property called “updates.EOC”)?
Thanks in advance!
