Error setting poster for a collection

[coding-blip]

It seems that the collection is created properly and items are added to it as expected, but I get the below error in my logs. I originally thought it was because I had manually updated the poster for the collection previously so I completely deleted the collection and re-tried.

Collection Christmas does not exist. Will create it.

=========================================

This is what I have for my config of the collection in the config.cfg file:

[Christmas]
source = https://mdblist.com/lists/cyberoxide/christmas
poster = https://www.publicdomainpictures.net/pictures/280000/velka/vintage-christmas-poster-15419982339El.jpg
frequency = 100
update_items_sort_names = False

Semi-related and possibly same issue as I got the same error I am seeing above, would it be possible to get an example of how to use a local file path for the posters? I tried the following line to mount a "posters" dir in the docker container:

- ${CONFIG_DIR}/emby-collections/posters:/posters

and then set the following in my config for the Christmas collection

poster = /posters/poster-name.ext

Confirmed, I get the same errors:

Exception occurred while uploading image: Failed to parse: .....
Failed to set poster for......

This is when running local image pulls so it's not limited to online sources as the OP described.

Bump on this as I am still seeing this issue in my logs. Thank you!
