Hello I am facing an issue where some of my requests are passing the client auth and some not.
I am using credentials auth. Init client example bellow (behaviour is the same if I pass the projectId too):

const client = new VehicleServiceClient({ credentials: { client_email: superServiceAccount, private_key: superPrivateKey, }, });

Example that works is client.searchVehicles(...)

Example that does NOT work is client.createVehicle(...) it returns Error: 7 PERMISSION_DENIED: JWT does not contain any scopes.

• This is fully strange for me because I used client.auth.getAccessToken() to get the token and then decoded it on https://oauth2.googleapis.com/tokeninfo?access_token=, and got this bellow which seems fine:
  { "azp": "107260674233372867632", "aud": "107260674233372867632", "scope": "https://www.googleapis.com/auth/cloud-platform", "exp": "1735572110", "expires_in": "3565", "access_type": "online" }
