WAS Slackbot Integration from WAS Landing Page errors when following the instructions

Question

"https://watson-personal-assistant.github.io/developer/further-topics/slackbot-integration/"

I am not able to make it work by following the steps on WAS Slack Bot Integration (above link).

1. My slack setting should be ok as I tried use the same ID and API token to connect to another program successfully.

2. I installed Python 3.7 initially, but downgrading to 3.6.2 as document suggested

3. "python3 bot.py" results as following - with exception stack

   Forests-MacBook-Pro:simple_WA_slackbot fmlin$ python3 bot.py
   Not On Bluemix...

During handling of the above exception, another exception occurred:

Connection failed. Invalid Slack token or bot ID?

Answer 1

Make sure you used the right Bot ID?

Did you set the user environment variable BOT_ID in the .env file?

Did you properly create the bot in slack using the instructions in the instructions https://github.com/Watson-Personal-Assistant/simple_WA_slackbot

Getting Your Slack Key

Go to https://YOUR_SLACK.slack.com/apps/manage
In the Search App Directory field at the top, type Bots
Click on Bots
Click on the Add Configuration button
Give your bot a unique username (Save this info)
Save the API Token
You will use these variables when creating your .env file as instructed in the below steps

Answer 2

Try running the /Applications/Python 3.6.2/Install Certificates.command program to install the root certificates needed to validate SSL connections, as it looks like your Python installation's SSL certificate verification is failing.

See more information about this program here.
