I've triple checked the SLACK_TOKEN and SLACK_WEBHOOK_URL values and both are correct and valid.

I tried deploying via command line but seem to have also encountered the same error:

Hi @calvinkw1 thanks for reporting this. I tracked down the error to a conflict related to an old version of the psycopg2 package. I just pushed a fix, and you should now be able to deploy without seeing this error.
