<' is an invalid start of a value

[anthonymag]

I am having trouble retrieving metadata for One Pace.

I have the One Pace plugin as the top choice for all metadata options in my anime library (which already existed and has other shows in it as well).

I did notice some errors in the logs when I try to do a force metadata replacement:

Jellyfin is setting this show as what it is finding (only for the show and show image though. The season folders and episodes are not matching): https://thetvdb.com/series/one-page-love

I did notice that those hex values in the file names don't match what the README has in their examples. Not sure if this matters?

[jwueller]

It seems that this is caused by https://onepace.net/ currently having issues. I'll see if I can at least improve error handling for this case if this happens again in the future.

Hi hab das selbe Problem, wollte OnePace jetzt auch hübsch haben. Solange die Website nicht online ist, gibts dadurch nur falsche metadaten?

[Roboron3042]

I am running into the same problem, but now https://onepace.net/ redirects to a discord invitation page. Will it ever come back?

[walsquared]

From One Pace's Discord server:

The site is currently down because of an issue with our hosting provider and is [now] redirecting people to this Discord. This is out of our control and we do not know how long the site will be down.

So for the time being, no more metadata from their api for us 🙃

[anthonymag]

Yep, I've just disabled the plugin (it was spamming logs) and hidden the One Pace folder from Jellyfin for now.

I periodically check https://onepace.net to see if it's back up.

[jwueller]

I'll treat this as a bug because the site being down should at least not cause any crashes.

[jwueller]

Track #66 for nicer fallback behavior.

[anthonymag]

Looks like the site is back. I did a quick test and got a different failure, presumably because of how they rewrote the site. I'm not sure if the plugin scrapes an API, but if it does it's possible they haven't finished writing it.
