Since today I receive the following error.

Me too.

I think I've found the reason for this Exception (I didn't test without an AppSourceCop.json file exists in the project).

@pri-kise and @tscottjendev , did this resolve the Exception?

pri-kise commented 2 months ago

I checked this project again and we have an AppSourceCop.json, but in this project we haven't specified the property mandatoryAffixes, but the property mandatoryPrefix.

Maybe this is the reason for the issue?

Update: I switched to MandatoryAffixes and now the error is gone.
