Server sync error: Unsupported Media Type

I’m not sure if this was a result of updated radarr versions or not (syncarr has been working perfectly for almost a year now), but I just noticed this upon migrating an installation to a new machine:

Adding “The Eyes of Tammy Faye” to instance “A” causes an Unsupported Media Type sync error:

syncarrR  | 2021-11-02 23:37:40,267 [MainThread  ] [INFO ]  syncing content from instance A to instance B
syncarrR  | 2021-11-02 23:37:40,267 [MainThread  ] [INFO ]  syncing content title "The Eyes of Tammy Faye"
syncarrR  | 2021-11-02 23:37:40,269 [MainThread  ] [ERROR]  server sync error for The Eyes of Tammy Faye - response: {
syncarrR  |   "type": "https://tools.ietf.org/html/rfc7231#section-6.5.13",
syncarrR  |   "title": "Unsupported Media Type",
syncarrR  |   "status": 415,
syncarrR  |   "traceId": "00-2f1640f44af6944a8fda79cd14258a88-693905c5c8680440-00"
syncarrR  | }
syncarrR  | 2021-11-02 23:37:40,269 [MainThread  ] [INFO ]  0 contents synced successfully

This sync error repeats itself every attempt. If I manually add “The Eyes of Tammy Faye” to instance “B,” the sync error disappears in the next sync:

syncarrR  | 2021-11-02 23:42:40,497 [MainThread  ] [INFO ]  syncing content from instance A to instance B
syncarrR  | 2021-11-02 23:42:40,498 [MainThread  ] [INFO ]  0 contents synced successfully

All of my instances are run in docker containers that were pulled either today or yesterday (Nov 1 2021), so they are current. If you need debug logs please let me know and I can post them here too…

I have fixed my build thanks to @mdinicola since the original does not seem updated anymore

docker pull maddemonoide/syncarr:latest

why you guys don’t use the List feature to sync from one Instance to another? https://trash-guides.info/Radarr/Tips/Sync-2-radarr-sonarr/

problem is that you can’t select a value lower than 6 hours to sync that list. so if a user is wishing a movie (e.g. by ombi) he has to wait up to 6 hours for the 4k version e.g.
