URL: https://github.com/apache/incubator-superset/pull/8859#issuecomment-566846650
@craig-rueda thanks for looking into this PR. I am getting into errors related to flask and python. This is strange especially when I have already configured the environment variable for the `postgres` docker. Need time to figure out this before it is ready for reviews.
