Mod is shown as downloaded even though SteamCMD failed to download mod

[Uncle-Sagbag]

I am using the steam-workshop-mods-status-keys branch.

SteamCMD is known for failing to download mods that are at least 1 GB in size. This means if one attempts to download a mod such as CUP or Operation Trebuchet, SteamCMD fails to download them. However, the issue is the web admin's mods page still shows a mod as downloaded though SteamCMD failed to download the mod. In some cases, the mod folder is created and the mod is shown on the mods page but the mod folder is empty.

This is the usual error when SteamCMD fails to download Operation Trebuchet:

From my research, other game server panels brute force past this issue. In other projects, the mod is downloaded repeatedly until it is completed as SteamCMD keeps the mod download progress on every attempt. Admins recommend redownloading a mod 5 or 10 times to get past this error. This could be a possible solution for your project, to have redownload the mod.

The current workaround is to manually upload the large mod to the server's game files.
