Error when launching

Someone may have already posted about this, but I can not type this error in and not sure what it's caused by haha. I'm new to making servers that require the things JD does so im a newbie at it. I have set everything up it seems like but when I launch, I get this error. I would expect it would have to do with the client but i'm not sure. If so, can anybody else send me a correct Zhuxian client? I followed this guide.
