I've just implemented mixpanel using segment,
All events that we track to segment are successfully sent to mixpanel. But I discover issue on event properties.
Some random unexpected event properties continue to appear in almost all of our events.
This random event properties come with "event properties value” as its property name and "another properties value” as its value. Making the number of event properties virtually infinite and therefore nearly unusable.
I have checked the event payload in segment, it doesn't have this issue.
Manually sending the payload through the event tester also doesn't create this issue.
Anyone have idea what is happening or what else I can do to debug this issue?
