Pixelmon Forge server not loading properly

[masguy]

Hi! I have basically no experience with installing minecraft forge servers, but wanted to start a local server connected to Hamachi and whatnot. I followed the steps laid out in this and everything went very smoothly; the server loaded and I could connect properly. However, upon joining I realized that the server had not actually loaded any of the mods installed and while I had the Pixelmon UI the server hadn't loaded the biomes or any of the mod's mobs. When I checked the "latest.log" I was met with this:

I tried reinstalling with the newest recommended 1.12.2 version of forge, and tried reloading the mods several times to no avail. What exactly is preventing the server from loading the mods, and what can I do to fix it? Due to my inexperience I'm probably missing something very basic, so any help would be much appreciated! Thanks!
