fix(datatypes): fixing nonetype error

[russorat]

Trying to run:

for e in ng.endpoint_configurations.list():
    print(e)

I kept getting TypeError: 'NoneType' object is not subscriptable

This fixes that issue for the objects i was using, but there might be more.

updated to also fix an issue when listing domain names:

it's definitely odd that None is getting passed in as props here, that shouldn't be happening. we'll take a closer look. did the domains error replicate with just nd.reserved_domains.list()?

yeah, i was just doing for d in ng.reserved_domains.list():
