My server keeps crashing with this error.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

A mod causes this.

Any idea what I might look for in a mod that could cause this?

From what I see, it seems like a mod is passing a nil parameter to register_globalstep. You may want to grep for that.

Look for minetest.after() calls which second parameter is nil.
