Error processing request.Thanks for any help.
RE: Error processing request. - Felixtw - 2025-08-10
I think the most relevant part of the logs is this bit:
Code:
System.ArgumentNullException: Value cannot be null. (Parameter 'request.App')This means we need to add an App parameter to the request. However adding one it still doesn't work and shows that error. this might be a bug report
RE: Error processing request. - Felixtw - 2025-08-11
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
