Happens to me for every indexer.

[lepinkainen]

I'm having the exact same issue with all my indexers, one using api and two using RSS. Started about an hour ago when the linuxserver.io docker image of jackett updated.

[garfield69]

confirmed.
AlphaRatio indexer works with Jackett 0.14.287 and is broken with 0.14.297
likely broken by b5a6aab894d45c2d43f71e4db3452e5932d77fa7

Gosh, talking about bad timing! I have just started learning Linux a week ago, so when things go wrong I thought I messed up somehow.... Only this time it wasn't me.

Is there any way to downgrade version? Would that help with the issue? Or we should just wait it out?

[garfield69]

if you absolutely cannot wait for the fix to be published, then download the appropriate package for your platform from https://github.com/Jackett/Jackett/releases/tag/v0.14.287
and don't forget after installing to temporarily turn ON from the dashboard the Disable Auto-Updates to prevent Jackett from replacing it with the broken version again.
then check back here accosionally to see when the fix gets published.

[andrep182]

Roger that. I want to at least confirm that my setup is working. I'll do that tomorrow and see. Thanks!

[vinaykapadia]

@andrep182 I'd just wait it out. It looks like a fairly straightforward issue, the devs here should have it fixed soon.

[garfield69]

its not b5a6aab894d45c2d43f71e4db3452e5932d77fa7, proceeding to revert and test other commits to isolate offender.

[cadatoiva]

I'm stepping through with the debugger to see what's causing it as well.

[cadatoiva]

Found the problem, now to see when it changed and get a fix put in.

[garfield69]

Jackett 0.14.299

[vinaykapadia]

Works great now, thanks everyone!

[andrep182]

confirmed working. Ya'll are awesome! Thanks.
