It pops out no errors, just doesn't do anything.

I haven't been playing BGs, and I'm only playing Wrath Classic these days. If someone wants to make a pull request to fix this, I will gladly check it out and merge it if it supports both Wrath Classic and mainline.

I've pushed a release which may resolve the issue. Can you please try it and report back?

I'm guessing it's fixed since nobody's reported otherwise in almost 2 years.
