Problem

API Analytics fails to generate reports and returns 500 Internal Server Error.

Traces show the below error while Analytics is starting up.

Resolution

The Analytics needs to have a listener named, "Reporter HTTP Interface".

The above error occurs if the default listener is modified or removed.

So the resolution is to create a new listener with name "Reporter HTTP Interface" or rename an existing listener to "Reporter HTTP Interface" in the Analytics Fed and restart Analytics.
