Invalid Event Fails Without Logging or Callback

[etchao]

Expected Behavior

If an event doesn't get tracked for any reason (in my case because of an invalid event property value), I would expect to be able to configure a way to get notified about it, either through logging or through the callback function.

Current Behavior

I was using the Amplitude client to track an event and noticed that it wasn't showing up in the Amplitude dashboard. After looking into it, it seems to be caused by a Python datetime object being passed as an event property (formatting it as a string resulted in the event being tracked). However, at no point did the library log an error (like it does for an invalid API key). Configuring a callback function also did not help - the callback function gets called for successful events, but not this particular error case.

Possible Solution

I'm not sure if the current behaviour is a bug or by design, but there should be some way for the developer to know about a call to Amplitude.track failing for whatever reason.

Steps to Reproduce

1. Track an event with a a Python datetime object as an event property value
2. No event gets tracked and it fails silently
