Trouble with getting debugger to work

Hi I am having trouble getting the debugger to work. I have installed the
debugger on edb postgres 10, 11, and standalone 11. Whenever I try to use
the debugger on pgadmin4, I either get a (TypeError: 'NoneType' object does
not support item assignment) if I try to debug directly or (TypeError:
'NoneType' object has no attribute '__getitem__') when i try to set a
breakpoint.

I have attached a screenshot of the stacktrace and some of the functions
involved and the text of the TraceBacks. Any and all help would be greatly
appreciated.

PgAdmin 4.4.9
Mac OS X 10.4.5
PgAdmin 10.9.2 / 11. 4. 2
Python 2.7
