Please provide more information as to how you encountered this issue

[jools772]

It happens each time I open the web page for the web ui, after ther daemon has been running for some time. It happened now again, and it's resolved by restarting deluge-web.service. There is really no other context, except that you open the web ui page.

Logs: deliuge-web: ​https://pastebin.com/rCk9EaRH

The error log also appears on the web ui page when trying to load it.

Here's the error written out since the pastebin expired:

builtins.KeyError: 'label/label.js'

The error is pretty obvious: the path 'label/label.js' isn't found in the list '_scripts'. See here:

​https://git.deluge-torrent.org/deluge/tree/deluge/ui/web/server.py#n371

The fix is to add one check:

if path in _scripts:

Would you please do this. I get the error quite frequently and it crashes the whole deluged daemon because of this.

[jools772]

The context is that one of the torrents is probably missing its label. I found out by looking at the count of torrents in filters window: ​http://prntscr.com/qhlqe2

The count of the totals didn't mwatch the number of unfiltered torrents, and I re-added labels to those all torrents manually.

It could be many things that lead to a missing label, but it would be good if the logs told us what happens instead of crashing. Maybe add that check and also log the name of the culprit in case there is a missing label. Could probably do this myself if I knew how to check out from trac.

Unfortunately I cannot replicate the issue however the problem you are reporting is a server script lookup issue, separate from actual torrents.

Looking at the code there should be no reason for order path value not be in the scripts dict but your error and forum users reporting it mean we will need to catch it, even if we don't understand it.

[Calum]

I think this might be the other way around that the keyerror is because the daemon has crashed since the label plugin scripts would not be available to the web server
