Hi

I am testing thehive-falcon on a Thehive test machine running RedHat 7.6 with python 2 and python 3. All the config files have been configured but I am getting below error when I ran the command python thehive_falcon.py falcon_config.json thehive_config.json. Please assist me as I am not python expert.

thehive-falcon]$ python thehive_falcon.py falcon_config.json thehive_config.json
