I am trying to use the SDM API and I am stuck at the authorize an account step in the device access guide. Instead of being redirected to my redirect uri I get a message saying no access to partner: information could not be retrieved. I am using the same google account for everything (GCP, SDM, Home). The account I am using is a member of the home in the app and I used the same account to setup OAuth credentials and device access project. I repeated the steps many times. I think there is a bug here.
It is likely that you might be missing a step in your project setup or credential generation. No access to partner might be due to several problems, though the most common ones include the account you use to register your project is different than the one you listed in your oauth configuration, or does not have access to the structure (home).
When you are creating an OAuth 2.0 Client ID on Google Cloud Platform, make sure the OAuth Consent Screen is properly configured (GCP Side-menu > APIs & Services > OAuth consent screen). If the publishing status is set to testing, you might need to list the account manually there.
If you still have issues after these steps, make sure to take a look at the Troubleshooting section of the Authorize an Account step for our docs. We also do have a codelab that walks you through step by step. You can start with a fresh account and follow through the steps in the codelab.
You want your publishing status to indicate in production, and the user type is set to external. If the publishing status is configured as testing, you might need to list your users explicitly in the OAuth Consent Screen page.
