Similar to #4002 but the issue here is that you cannot override with an empty value the vars provided in .env files.

Based on the discussion in #4002 it sounds like this might have something to do with
dotenv-expand. Can you try removing that dependency from your project and testing again?geritol commentedon Nov 17, 2018
Removed
dotenv-expandfromreact-scripts/config/env.jsline 43 and the empty override behaves as expected!iansu commentedon Nov 17, 2018
Thanks for checking that. Can you create an issue with
dotenv-expandand reference this issue so we can track it?stale commentedon Dec 17, 2018
