when debugging python which error to look at first?
Got this cool pan-tilt hat for my Raspberry-Pi by pimoroni. Comes with some web interface code written in flask. The service starts up, but when I click a direction. Code:
pi@raspberrypi:~/pantilt-hat/examples/pantiltweb $ sudo python3 pantiltweb.py
* Running on http://0.0.0.0:9595/ (Press CTRL+C to quit)
* Restarting with stat
* Debugger is active!

I think it is that first error on the call to get /api/89/
I get a 500 http return code. I notice I don't have that directory.
