Please advice.

I would try request.session.get('cart_id', None) instead of
request.session['card_id'].

Both act the same if the key exist in the dict. When the key is
missing, the first return the second value (None in this case) while
the second raise a Key Error exception.

Negative.
First, this is part of the 3rd party app "doorsale". Secondly, at this
stage in the order process a cart id SHALL be present in the session and
as such we need to error out hard and not suppress.

This is a configuration issue by OP or a bug in the software, but I'm
not familiar enough with doorsale to say which. At first glance though,
the view handling it and the views preceeding this stage look solid.
