KeyError 'Token'

I'm getting

KeyError: 'token'

My settings are:

BOT_URL = 'http://mattermost.domain.com/api/v3'
BOT_TEAM = 'dev'

I have tried the suggestions in #2 and #16, and tried other version values, but this has not helped.

I'm running mattermost v3.2 on Debian stable

Fixed by changing the BOT_URL to

BOT_URL = 'https://mattermost.domain.com/api/v3'

I just want to add that I had the same issue and was at a loss since none of the proposed solutions were working, I then printed out p.text and found that the error was that the bot user's email was not verified. I had enabled email verification for everyone after the bot went live and hence it was getting blocked. Just putting this in here in case it helps someone.
