Unable to properly transfer Eagle files to Fusion360

[jmktym]

I'm trying to import Eagle .brd and .sch files into Fusion360. When I try to upload the files, I get the following error:

Warning: Loading D:/NS-8 PCBs/MR SAT Motherboard REV D.brd ...

Warnings:

line 235: missing attribute 'vertex' in tag <polygon>

When I create an electronic design file and reference the board to the schematic, I get the same error but I can see the board and schematic. However, there are no traces shown. When I try to push the board to Fusion360 through Eagle, I get the following error:

Error connecting to Forge, please try again later.
