Error with service startup

[x] I’ve read the Troubleshooting Wiki, my problem is not described there and I am already using the specified minimum bluez version.

Describe the bug Manually running sudo ./gateway.py -d works fine and I can see correct output. This is when I try to start the service:

A couple issues here. Looks like the logger cannot load the yaml module. It also says something about start request repeated too quickly.

I had issues getting the service.sh started as well. I had to do #194 by comment out lines 3-9. Before doing that, when executing ./gateway.sh, I ran into btle.py errors, which was fixed with setcap…probably not very secure.

sudo setcap 'cap_net_raw,cap_net_admin+eip' /usr/local/lib/python3.7/dist-packages/bluepy/bluepy-helper

I also had to modify the bt-mqtt-gateway.service to add ExecStartPre=/bin/sleep 30 because the service failed to start when system was reboot. Probably needs some python service started first.

similar problem on rpi0w but starting it within docker. up until now i was not able to get out any logs from the container as it keeps restarting.
