Symptom

Symptom

When attempting to login, the following error is returned in SAP Customer Data Cloud (CDC) logs:

{
  "callId": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "errorCode": 400302,
  "errorDetails": "Error executing Extension Point",
  "errorMessage": "Operation failed",
  "apiVersion": 2,
  "statusCode": 400,
  "statusReason": "Bad Request",
  "time": "2025-06-30T12:50:31.842Z"
}

The error indicates that the extension webhook configured on the onBeforeLogin event fails to execute, although testing the webhook endpoint externally (e.g., via Postman) works successfully.
