Hi, is this step happening when you try to configure a new n8n credential for Google (after having entered your client ID/Secret that you received from your google cloud project &client activation, and finally validating the n8n credential with the “SignIn with Google” button)? The n8n Google oAuth doc is quite explicit.
N.B.: if you don’t publish your googleCloud on purpose created application, it stays under the “Test” status. If so don’t forget to add your Google account as a Test User (in the [audience] menu of your googleCloup Project API&Serivces/Client configuration cf. https://console.cloud.google.com/auth/audience)
Can you please tell us a bit more on what exact action you get that message and if it is generated on a node execution or when validating your n8n credential for accessing google?
As from your answer you did try everything, so you confirm that you have:
a google cloud project
with a validated OAuth 2.0 Client (so you have your client ID and client secret)
a configured OAuth consent screen
In n8n you did create a credential for accessing google API that you have tested and validated activating the “SignIn with Google” button in the n8n credential configuration screen.
If theses steps have been followed, without error where do you get the error?
So to confirm, which env vars are you using? It seems u have ngrok, so which URL do you access the GUI from (confirm its not localhost), and which URLs do you see on the webhook node?
In essence, you need these, it would appear inside your composer file:
You can either place actual values in the .env file or docker-composer
environment:
- N8N_HOST=${SUBDOMAIN}.${DOMAIN_NAME}
- WEBHOOK_URL=https://${SUBDOMAIN}.${DOMAIN_NAME}/
