I seem to be having a problem similar to [1] on a recently built plex docker instance, in that even when movies are correctly matched, the poster image is never correct (e.g. a random scene from the movie) or is blank (usually blank).
I’ve tried clearing the caches, metadata, and media folders under "plex-docker/config/Library/Application Support/Plex Media Server/", but no luck.
I’m seeing quite a few of these in the logs, maybe related?
"ERROR - Metadata /system/agents/media/get request failed with code: 500: http://127.0.0.1:36445/system/agents/media/get?guid=com%2Eplexapp%2Eagents%2Eimdb%3A%2F%2Ftt1216475%3Flang%3Den&mediaType=1&url=metadata%3A%2F%2Fposters%2Fcom%2Eplexapp%2Eagents%2Eimdb_3ebad235db9abdc55c2a01f95e76106ed7a58777"
What are the next steps?
