> {{ListenHTTP}} depending on the MIME type, will unpack received content
> automatically. For example, if using {{InvokeHTTP}} with a flowfile packed in
> {{FlowFile Stream v3}} format, with the {{mime.type}} attribute set to
> {{application/flowfile-v3}}.
> When {{ListenHTTP}} receives the payload, it will interpret the MIME type and
> if it matches a well-known value (i.e. {{application/flowfile-v3}}), the
> content will automatically be unpacked by this processor.
> While that's a handy feature, it is potentially confusing as this inline
> unpacking behaviour isn't documented, and a reasonable expectation is that
> one needs to {{UnpackContent}} separately in a subsequent processor.
> Recommend adding some use case documentation to {{ListenHTTP}}, to avoid
> confusion.
