I mean that I am sure that the access token is the same for each, and that the same code I am running locally which works, is the code which is deployed and not working. what could be different if the access token and code are the same?

I don't have full context on your different environments of course, but there could be non-obvious differences, e.g., in the versions of the platform, programming language, network client, etc., being used, exactly how the access token is stored/retrieved, or so on, between the different environments.

 

To troubleshoot this, the next step would be for you to inspect the request being made from the deployed environment.
