I'm facing the "same" issue since few days.
Search in the Jackett interface works great, but won't work when I add it to radarr (the test is looping forever)

Also, Jackett version is 0.11.348.0

[rkmfl]

Yes, I get the same thing, ever since the 0.2.0.1344 update on 2019-05-05

I have also uninstalled and re-installed as a fresh copy of Radarr, with same issues.

Since then I've moved to another system and installed Radarr, then copied over my settings, same issues.

[1990clb]

Has anyone found a workaround for this issue? Got everything set up but can't add any indexers.

[rkmfl]

@1990clb - Are you saying that you receive the "Couldn't process release.: Object reference not set to an instance of an object." error, or something else? Or can you paste your specific error?

[1990clb]

Sorry, I should have been more descriptive. I'm having the same issue as reported by Buri, when adding torznab as an indexer I receive the error:

[galli-leo]

Where did you guys get this version from? Did Radarr auto update to this version itself? The version you are running on is a non supported experimental branch.

[1990clb]

Not sure about others but I installed it from here using the "preview" tag.
https://hub.docker.com/r/linuxserver/radarr

[Buri]

Yeah, the same

[galli-leo]

Well then that’s expected

[1990clb]

Where can we report issues with the "preview" version?

[rkmfl]

@1990clb -
To clarify, @galli-leo (the primary dev) is saying that your fix will be switching to a supported version.

To do this, go to:
Settings > General > Updates : Branch

You've got a few options you can enter here, any of them will work as long as you remove "preview".

The popular choice is "develop" (for more frequent release but possibly less stable). I believe the other options are likely "master" (more stable/less frequent) or "prod" (production - likely same as master for Radarr).

Once you change that, make sure to update and confirm you are on the May 5th release (Click "System > About" see "Version" which should be 0.2.0.1344 for the "develop" track.

[Buri]

Well, this is all nice, but this bug still needs to be solved in the future if this version is ever to be going live. Dont get me wrong, this is not a support request ticket, this is a bug report and I don't believe that "switch to stable version" is correct resolution.
I don't mean to sound like an ass, just trying to help.
