The community member is having an issue with a block that is not responding. Other community members suggest trying to send a JSON body with some value, such as { "test": "123" }. This seems to be the solution, as the block only works when a JSON body is sent. The community members also note that this information should be added to the documentation, as it is not currently mentioned. Additionally, there appears to be a bug that the block should work even without a body, and a fix is being pushed.
