Solutions

1. Lower max_body_size to 10MB or less.

Example fix

webhook_config = {'max_body_size': '10MB'}

When it happens

Trigger: Thrown at api/apps/restful_apis/agent_api.py:1946 when the library encounters an invalid state.

Common situations: The configured webhook body limit exceeds the hard 10MB cap; reducing the limit prevents this error.
