Failed to parse response from Sonarr - "missing field `statistics`"

[abstrakct]

Summary

Hi! And thanks for this nice application!
Not sure if this should even be considered a bug - it's an edge case for sure, but I report it in case you want to handle it.

So, I tried managarr for the first time recently. I have a simple setup with just one radarr and one sonarr instance.

Radarr works fine, but in the Sonarr tab I get this error:

Failed to parse response! reqwest::Error { kind: Decode, source: Error("missing field statistics", line: 4162, column: 7) }

It is only on the "Series" view. Other data is fetched without problem, like indexers, downloads, etc.

Same error if I run "managarr sonarr list series"

So I dug into the response from sonarr, and after wrangling the json with jq and grep, I finally found two seasons where the "statistics" field was missing. These belonged to some shows added many years ago, and for some reason both had a "season 0" with basically no data:

{
      "seasonNumber": 0,
      "monitored": false
}

I solved it by clicking "Refresh & scan" on the two affected shows in Sonarr. This made Sonarr remove these empty seasons, and Managarr now works perfectly 🥳

Reproduction Steps

Might be hard to reproduce on another system.

I'm running mangarr in docker on linux, image tag "latest" as of 2025-03-01, so should correspond to v0.5.1.
Sonarr is also up to date, v4.0.13.2932.

Should be possible to artifically reproduce / add to unit tests by using a json where one of the seasons have no "statistics" object, as shown above.

Thanks for taking the time to fill this report! It really helped me dial down on where this happened!

It took me a sec but I do know what happened. I'll start working on this now just to be safe.

For anyone else experiencing this issue and wanting to fix it prior to the next release, you can use the develop branch and install Managarr via Cargo as follows:

cargo install --git https://github.com/Dark-Alex-17/managarr --branch develop

Just note that there's no stability guarantees on the develop branch.
