1 Mod continues to fail to load

[HalcyonsOmen]

Every time I attempt to start my server up, I run into an issue with 1 specific mod. The mod won't load correctly and leads to a crash report. I referred to a previous post in the discussions to which I was led to https://docker-minecraft-server.readthedocs.io/en/latest/types-and-platforms/mod-platforms/auto-curseforge/#exclude-client-mods . I attempted to follow the documentation, but I don't know any proper syntax and need help making this work. Currently I've tried
environment:
CF_EXCLUDE_MODS: 421897
environment:
CF_EXCLUDE_MODS: particlerain
environment:
CF_EXCLUDE_MODS: |
/data/mods/particlerain-4.0.0-alpha.3+1.20.1-forge.jar
I'm not sure what the correct way to set it up is, because the documentation didn't have an example for what I was looking for. The documentation mentions passing a comma or space delimited list of project slugs or IDs, however I am not knowledgeable of how to do that. Let me know what the proper syntax would be for this thank you.

The first two are formatted correctly. Make sure to also temporarily set CF_FORCE_SYNCHRONIZE to "true".

While waiting for a response I've done some messing around. I can test if that does fix the issue I was having, but I found a way around. Looking at documentation, I found there was a method for running "custom" modpacks. I took the zip file for the modpack I plan on using, imported it into curse forge as a custom pack, removed the mod that was giving me issues, exported as zip, and used that zip with CF_MODPACK_ZIP: and set the slug to the slug of the modpack I will use. I just now got the server to boot with that method. When I was trying to previously exclude that one mod, I would either get an error from the file still being in my mods folder or I would get a loop of the server trying to download that missing mod when I had to mod removed from the folder and the slug excluded. I appreciate the help and I will test CF_FORCE_SYNCHRONIZE later.
