Error after adding mods to forge 1.19.2

[IniJamiel]

I made a docker container with TYPE=FORGE and VERSION=1.19.2 I have tried to use volumes to copy the mods, as well as copying the mods to /data/mods manually. But, I still get this error regardless of versions. Is there any steps that I miss? using curse modpacks seems to work in this environment. Running forge server without mods seems to work just fine

Exception in thread "main" cpw.mods.niofs.union.UnionFileSystem$UncheckedIOException: java.util.zip.ZipException: zip END header not found
Caused by: java.util.zip.ZipException: zip END header not found

It sounds like the jar/zip file is corrupted or not actually a zip file. I know sometimes if a download fails, it'll put the failure page HTML in the file instead of the expected binary content.

i have the same problem, any idea how to solve it?

I'm kinda stuck in the same place. Using ATM9. MC ver. 1.20.1. There are over 400 mods installed, and the error doesn't really indicate which one may be causing a problem (and it took me 6 tries and 2 hours to download them all because of the CurseForge rate limit with API calls)

That is ideally a problem for the modpack author to solve. The only advice I can provide with respect to this image is to make sure you do not have a restart policy enabled. Otherwise you will hit the API rate limit more quickly.

I was able to do a find $PATH_TO_MODS -name "*jar" | xargs -L 1 zip -T | grep error | grep invalid
to find out which jars were corrupted (it was like....a third of them), delete them, then restart the container to have it re-download them. Took about 3 loops of that to finally get all of them clean. Still have the error, but I am heading in the right direction. I won't enable the restart-policy until I got this fully working.

The issue seems to be CurseForge downloads getting corrupted during the download phase, not even the modpack publisher.

Hey everyone, not sure that this issue can be related to forge issues, but please, check what I wrote in different issue:

In my case, the problem was not with mods, but with forge and their bad installation.
