rtsp://XXXX/: Invalid data found when processing input

With the trace log level the command ends like this:
[rtsp @ 0x7fab40000b80] line='x-Dynamic-Rate: 1'
]rtsp @ 0x7fab40000b80] ret=1 c=0d [

I suspect it is something connected to the "empty line". Is there a way to
skip this error ot has someone any clue?

Best
