MSD 365 Web Portal - Employee Self Service Portal - Can we check where exactly we are getting " The form could not be submitted for the following reasons: You don't have the appropriate permissions." error?

Hi All,
I was trying to edit few permissions on Employee Self Service Portal. After doing those changes , it started giving me below error while creating or update case records.

The form could not be submitted for the following reasons:
You don't have the appropriate permissions.

Is there any way to check , why exactly we are getting this error ?

I know I'm getting error because I have set some permissions which are not allowing me to save or update the record . But I want to check , for which entity this is occuring ? I don't want to revisit all the permissions and revert it back to one by one.

As like we debug code and we get the issue pointer ,where exactly it is breaking. I need the same thing here.

I hope you have understood my question.
