I can't reproduce this is with master or 29.1, but I can with 28.2.
This is the backtrace in 28.2:

Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)
  forward-paragraph(1)
  fill-forward-paragraph(1)
  fill-region(1 520 left t)
  easy-mmode--mode-docstring("MWE mode" "Mwe mode" mwe-mode-map mwe-mode)

I guess you hit a bug that has already been fixed.

Michael.
