Error processing request.

resolved this by looking at jftui's source. you should have x-emby-authorization header set, something like this:

Code:

curl -X POST $JF/Users/authenticatebyname \
          -H 'accept: application/json' \
          -H 'Content-Type: application/json' \
          -H 'x-emby-authorization: Mediabrowser Client="mycustomclient", Device="mydevice", DeviceId="myid", Version="1.0.0"' \
          -d "$data" \

hope this helps you OP and anyone else who gets this
