Hi,

Hey @Fadhli_Fatahillah when you set up your credential set what did you specify as the redirect URL? You should be matching this value to the “Redirect URI” provided once you “Authorize Connection” (should be something along the lines of https://console.cloud.google.com/connectors/oauth?e=13802955&project=myProjectHere)

Thanks!

Matt

Hey @Fadhli_Fatahillah

It typically occurs when the redirect URI used by application doesn’t match the one configured in the Google Cloud Console.

Please confirm if you’re using OAuth 2.0 client credentials. If yes, could you please check:

  1. Navigate to https://console.cloud.google.com/apis/credentials

  2. Locate your OAuth 2.0 Client ID.

  3. Under `Authorized redirect URIs`, ensure that the URI your application is using is listed exactly— ensure case sensitivity, trailing slashes, and whether it uses http or https.

    For example, if your application is using:
    https://<your-domain>.com/auth/google/callback
    URI must be included in the list of authorized redirect URIs.

    Please double-check the URI for any discrepancies and update the configuration accordingly.

Could you please confirm if the issue has been resolved, or are you still experiencing it?
