FAQ: Triggering the “Invalid HTTP Message” IDP Rule in Forum Sentry

A request or response message might trigger the “Invalid HTTP Message” IDP rule in Sentry resulting in the “No Matching Request Filter” error. This is a very common support issue that is easily identified and resolved.

To resolve the problem, ensure that the client is specifying the correct Content-Type HTTP Header and/or using the appropriate HTTP Method. Alternatively you can adjust the HTTP Request Filters defined for the policy.
