hi @EvovSo ,

There is likely an issue with how you are creating the access token. I'd recommend using this as a guide to make sure you are following the right steps. https://developer.adobe.com/developer-console/docs/guides/authentication/JWT/

Alternatively, you could switch to use our new authentication method -- see more info here https://developer.adobe.com/developer-console/docs/guides/authentication/ServerToServerAuthenticatio...
