Hi @lior1,
Welcome to the Auth0 Community!
The error you have observed is triggered when using a Machine-to-Machine client_id. At the moment, M2M is not supported by Organizations yet.
We have included Organization support with M2M clients on our roadmap, but unfortunately, there is no ETA.
Hoped this answers your questions.
Please let me know if there’s anything else I can do to help.
Thanks.
