I am trying to connect sonarr to prowlarr, and I get the following error when I try to add sonarr. I dont understand the logfile at all to be frank.
Request Failed. POST /api/v3/indexer/test: Object reference not set to an instance of an object

EDIT: I have found the issue. It was a simple case of an out of date docker container. Changing the repo from "arch-sonarr:v3" to "arch-sonarr:latest" upated the version number and fixed the connection.
