[Bug] Sonarr download trigger returns 404

[trusta]

Describe the Bug
On the iOS app, doing a manual search for an episode of a TV show, and then attempting to start downloading that release, results in an error: DioException [bad response]: The request returned an invalid status code of 404.

I've reproduced LunaSea's API call in postman to get more details on the error returned by sonarr :

I compared the call made by LunaSea and the sonarr UI and found a difference. Sonarr UI adds the episodeId in request body. In this case, it's particularly useful.

To Reproduce
Manually search for a series episode for which the series is not automatically recognized via the file name.

Sonarr marks the episode as Unknown Series in its interface :

Try to download the file in LunaSea.

Expected Behaviour

I'm expecting the download to start.
