Guys, I created a webhook and enabled it normally in the chatbot integrations. I created a post request in Postman just to test. The request status is 200, but the response content comes with an error message. This happens only when I send it with content in the body. I've tried with real content that would be sent by the other system, and also with simpler content that is even in the official documentation. It always gives this error message. It only doesn't give an error if there is no content in the body. How can I solve this?
