Solutions

1. Send the request with the Content-Type required by the webhook configuration.
2. Adjust the webhook content_type setting if the caller cannot change.

Example fix

headers = {'Content-Type': 'application/json'}

When it happens

Trigger: Thrown at api/apps/restful_apis/agent_api.py:2128 when the library encounters an invalid state.

Common situations: The webhook caller posts with a Content-Type different from the configured expectation (e.g. form data instead of JSON); aligning the header prevents this error.
