Seems like a workaround/solution is to instansiate the session_state variable, as below

            # For address family: VPNv4 Unicast
            m = p31.match(line)
            if m:
                session_state = ''
                if 'address_family' not in  parsed_dict['neighbor'][neighbor_id]:
                    parsed_dict['neighbor'][neighbor_id]['address_family'] = {}
                address_family = str(m.groupdict()['af']).lower()
                
                if address_family not in parsed_dict['neighbor'][neighbor_id]\
                    ['address_family']:
                    parsed_dict['neighbor'][neighbor_id]['address_family']\
                        [address_family] = {}

                parsed_dict['neighbor'][neighbor_id]['address_family']\
                    [address_family]['session_state'] = session_state.lower()
                if 'state_reason' in parsed_dict['neighbor'][neighbor_id]:
                    parsed_dict['neighbor'][neighbor_id]['address_family']\
                    [address_family]['state_reason'] = \
                        parsed_dict['neighbor'][neighbor_id]['state_reason']
                continue

Company policy won't allow me to paste the configuration on public GitHub. Happy to raise a TAC, if you can direct me what category to raise it under.
