@millis I just did it again without issues…
the error shown seems to indicate that you picked the wrong app type
the credentials.json (that you downloaded from google) should look like this
{ "installed": { "client_id": "cccccc", "project_id": "ccccc", "auth_uri": "https://accounts.google.com/o/oauth2/auth", "token_uri": "https://oauth2.googleapis.com/token", "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs", "client_secret": "ccccc", "redirect_uris": [ "http://localhost" ] } }the code is looking for the “installed” item
