Demo bot crashes when trying to send a message - channel_type = channel['channel']['type'] - KeyError: 'channel'

[mechastorm]

Where should I debug this issue I am having? I had spun up the bot from the demo installation instructions.

• It can join the channel
• I can manually log it in the channel as well
• the bot starts up fine

The minute I try to send a message in the public channel

• example: just saying hello
• bot detects
• attempts to send a response
• crashes

The crash log

Is this a permission issue? My bot account can talk in the public channel with no issues when I manually log it into the system. But through the mattermost bot, it crashes.

My sample config

DEBUG = True
SSL_VERIFY = False
BOT_URL = 'http://my-mattermost-server/api/v3'
BOT_LOGIN = 'my_bot_username'
BOT_PASSWORD = 'my_bot_pass'
BOT_TEAM = 'my-channel'
