OK! I succeed to build the docker image and now my nostr index is available in Prowlarr and pushed to my Sonarr instance. I can well see the torrents into the torznab feed from Prowlarr but I have an error when searching from Sonarr (with a tv show and episode number query joined) :

The weird stuff is the request seems to be working with 1337x index. Do you have the same behavior maybe?
