Hello Karol, I too experienced this problem. The solution, for me at least, was to recompile the client. This is actually documented in the README that comes with the client (Java client in my case), specifically it states:
Every time you modify a file in src/main/resources, you must have Maven > recompile the project to pick up the changes. If you copy it to your home > directory, you will not need to recompile every time. After copying the auto-generated Client ID into my ads.properties AND recompiling the client, I no longer received ADD_OPERATION_NOT_PERMITTED in response to the mutate (add) request. I hope this helps.
