This is not a bug on our side. You need to set the header Content-Type to application/json. We reserved GitHub for verified bug reports and feature requests. If you need additional help, please ask on the forum.

Also, you can see the same behavior in 5.4.1 if you set http.content_type.required to true. This is the default in 6.0.0 and is unchangeable.
