Webhook Error

So I created a webhook module on my scenario. But then when I run it, I get this error:

The operation failed with an error. [401] Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See Integrating Google Sign-In into your web app  |  Authentication  |  Google for Developers.

How do I solve this? The webhook is connected to relevance AI.
