Malformed OAuth2 Access Token When Deployed to Vercel
So I just started using dropbox for a nextjs/react app and everything works fine exactly as it should when I run it locally, but when I deploy to vercel I get a 400 code and the 'Error in call to API...
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?

Dropbox StaffI 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.
