Unix args file?

[chrome lichen]

I'm trying to upload a custom mod pack and every time I go to start the server I get the following error:
sh -c 'cd /home/container && ARGS_FILE=$(find libraries/net///*/unix_args.txt 2>/dev/null | head -n 1); if [ -n "$ARGS_FILE" ]; then java -Xms128M -Xmx8192M -Dterminal.jline=false -Dterminal.ansi=true ${CUSTOM_ARGS} @"$ARGS_FILE" ${CUSTOM_ARGS_END}; else echo "ERROR: Unix args file not found."; fi'

and the server will shut down. Help please!! 😦

Custom Forge is selected in the Minecraft Jar menu - which means "I will bring my own Forge server files."

But the error says the Forge server files were not uploaded.

I copied over all the folders from the extracted forge folder

so I'm not sure what file I'm missing 😦

Extracted Forge folder?

Forge server files usually come from an installer.
