graphQL API down after duplicating object class but change its endpoint name

Hello everyone,
We have experienced before that if you have two object classes with the same endpoint name the graphLQ api stops running. Today we duplicated an object class and after that changed its endpoint name, but the graphQL api is still down.
Do you know what other issues could be related to it?

Thank you

In Appfarm version 23.3, the Duplicate object class-function does not work as intended, causing this error. The problem is found and will be fixed in the next release (23.4).
