Flutter Google Sign In Couchbase Authentication Code Flow

As we are migrating our app from Firebase to Couchbase, we also need to change the authentication part. We are using the google_sign_in package and would like to continue using it to have the native Google Sign In popup. Using the package we can get a serverAuthCode, which from my understanding we can then send to the _oidc_callback endpoint of Couchbase Sync Gateway. First I had to set disable_callback_state to true in the Sync Gateway configuration ("DisableCallbackState determines whether or not to maintain state between the /_oidc and /_oidc_callback endpoints."). However, when I now send the serverAuthCode to the _oidc_callback endpoint, I get the following error with status code 500:

body: {"error": "Internal Server Error", "reason": "Failed to exchange token: oauth2: cannot fetch token: 400 Bad Request\nResponse: {\n \"error\": \"invalid_grant\",\n \"error_description\": \"Bad Request\"\n}"}

I assume it is because the login was done using the package and not through the browser with a redirect to the app afterwards. Now I have no idea how to do this correctly though, that I sign in with the google_sign_in package and then use the code to get the tokens from the Sync Gateway. I can't find any helpful information for this problem.

I would be very happy if someone could help me, possibly in a call. Maybe this way something like this can be solved faster.
