Error starting ribbit-backend_ribbit_1, following readme instructions

Hi, I tried to follow along with the readme, but running into 2 problems:
1. A warning on the plaid environment selection - .env is set to export PLAID_ENV=sandbox, but this doesn't seem to be working. The same error occurs with and without double quotes, as well as for the other options.
2. An email address seems to be needed, but it isn't clear which config file this should be added to.

Thanks for your help!
