Build error (Remote Workspace Setup)

I'm using the latest snapshot of MCreator (2021.1), and set up a remote workspace, since I needed to fix a few bugs and add some things, so I tried editing an entity element (after pulling from the remote workspace), and it tried to build but it failed and I'm not sure why. I also don't see any of the other elements that are supposed to be in the mod elements tab in MCreator, only the erroring one is there after I get the build error, so that's weird.

This is the remote workspace on Github: https://github.com/jadenquinn/dreamsdev

The error/log: https://pastebin.com/C8rqeN8p

Thanks!
