Description

npx amplify sandbox process not exiting gracefully on control + c. It behaves randomly incorrect

1. not listening to control + c event when npx amplify sandbox is in error state
   

2. control + c event skips all the way without letting me respond to cleanup prompt
   

Most of the time this behavior happens when deploying sandbox env errors but occastionally noticed it on success as well.

I'm able to reproduce this by removing email from the defineAuth template, running amplify sandbox, which in turn produces an error. When attempting to ctrl+c I see the same issue

Error: setRawMode EIO

[josefaidt]

reproduced the second issue where the sandbox is hanging on to the process. I think my sso session expired and I saved a change in auth, then encountered the error below. When I encounter this I am forced to close my terminal.

The CloudFormation deployment has failed. Find more information in the CloudFormation AWS Console for this stack.

The issue is with the yarn not respecting SIGINT signal and just exiting right away leaving the children (sandbox process) hanging. because the parent process (yarn) is exited, the associated STDIO for child are also closed, so when the prompt tries to send something to stdout it crashes with the error setRawMode EIO.

I had better luck with yarn 1.22.22 where atleast the shell didn't hang and was still usable. but doesn't look like we can do anything until yarn fixes that bug.

[Amplifiyer]

this feature was removed. We don't have a prompt on ctrl-c anymore
