When trying to add the campanion mod in a dedicated server forge version 43.2.11:

I got this error:

I'm having the same issue, with the same version of campanion and minecraft. Log looks just like mine as far as I can remember. I can provide an additional log from my crash as well, and what forge version I've been using, if it's helpful.
