[Solved] /core/me returns error "NO_API_KEY"

This seems like the opposite of what it should be doing, because this end point does not accept an API key:
https://invisioncommunity.com/developers/rest-api?endpoint=core/me/GETindex

I am using the same code to access other API features with no issues. IPB 4.5.

Edit:

This is a generic error that also gets used if the authentication token is wrong. There's no problem.
