Hello ,
i have an issue to generate a request to veo 3 from my n8n hosted on aws .
Authorization failed - please check your credentials

Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See Integrating Google Sign-In into your web app  |  Web guides  |  Google for Developers.

can you help please ?

Hey,

This is usually a credentials issue. Quick fix:

Go to Google Cloud Console

Create a new Service Accoun

Enable Vertex AI API for your project

Download the JSON key file

Add it to your n8n node settings

Can you share a screenshot of your authentication settings in n8n? It’ll help me see what might be wrong with the current setup.
