pytile: "TypeError: 'NoneType' object is not subscriptable" for Android devices

Hi @bachya, Thanks so much for this helpful app. I’m trying to get set up to use it in a research study, but am having trouble getting off the ground.

When trying to run your example code, i get the following response:

{“version”:1,“revision”:1,“timestamp”:“2020-06-30T13:16:15.732Z”,“timestamp_ms”:1593522975732,“result_code”:0,“result”:{“message”:“invalid app version, version=null, app_id=null”}}

Seems like DEFAULT_APP_VERSION is hard-coded in client.py? Admittedly an api novice, so any help is greatly appreciated
