Error choosing spawn on location.

[Art1st Art1st]

I made my map in WorldEd+TIleZed, did everything according to the guide from the official forum.
I set the spawn points.

But, when I select my location and click "Next"
I get this error in the console:

What could be the problem?

Was about to post a simular error, I also keep getting a stack trace error when trying to open up my map for testing.
