Any progress on finding the issue? It seems the bug is not platform dependend.

I did not have time to look into this

I've also been debugging this for the last 24 hours. It appears the issue is here: https://github.com/facebook/create-react-app/issues/8688

React-scipts added some shutdown logic in a patch release that's broken and causing issues in both Docker and CI environments.

I have the same issue in CircleCI: https://app.circleci.com/pipelines/github/dominikwilkowski/bronzies/122/workflows/aafbb9bc-9d96-4836-8204-2c03a545d5c0/jobs/247 (Also using CRA)

Seems related. What's curious though is that when I ssh into the instance and run the same command that fails in ci, it runs without issues suggesting that the ssh session keeps something alive that's otherwise shutdown in ci.

I'm facing the same issue 😭

FYI, I was running into this exact error after upgrading react-scripts to 3.4.1 while running Cypress tests in an Azure pipeline with start-server-and-test. The fix for this issue is to add an env variable of CI=true to your environment variables

[dominikwilkowski]

Just tried the solution from @DAnselC but it still fails the same way in circleCI... https://app.circleci.com/pipelines/github/dominikwilkowski/bronzies/125/workflows/79b6d12f-9ef7-429b-8df6-ee61b7d53662/jobs/254

Thanks for sharing though. Might help someone else with Azure...
