[BUG] Jellyfin Backend Additional Options Empty Array

[Viv-Rajkumar]

Describe the bug
For a jellyfin backend, unable to add additional options via the UI following instructions from -> FAQ note

To Reproduce

• Edit jellyfin backend options.
• Select additional options
• choose any option. hit the + icon

Expected behavior

• Option added above picklist so value can be set

Additional context
Brought this up in Discord and seems issue is due to options key in that json when empty being an array [] vs {}. thus the Ui action to append obj key fails.

Workaround sorted this issue -> "Backends > select backend > View backend libraries." -> toggle on/off any library, this gets the json value type sorted and then original steps worked ok.
