C3W3 Lab1 Environment variable $DATABASE_URL not set?

I set the PostgresEndpoint and RedshiftClusterEndpoint in the env file and saved it down but what do I do with this message?

Hello @Chris61
When replacing the values for RedshiftClusterEndpoint and PostgresEndpoint in the src/env file, make sure to copy the exact values from CloudFormation. These values should not include http:// in the beginning or / at the end. Your redshift_connection_url should look like the following image.

Thank you!
