As the preview tag has been deprecated and the latest tag is now installing the V3 version of Sonarr I switched to the latest tag. On startup, however, Sonarr generated the following error " System.ArgumentException: Requested value ‘Docker’ was not found."
When I looked on the Sonarr forums they indicated this occurs when a V2 version of Sonarr is trying to attach to a V3 database. Switching back to the preview tag resolved the issue however I am stuck on a deprecated tag now.
