Error: server closed unexpectedly on gitlab CI

Bug report

Hi,

• version
  1.14.0
• platform
  node 18.12.0 on linux via docker image cypress/browsers:node18.12.0-chrome106-ff106 in Gitlab.CI
• expected behavior
  After tests are finished to stop the child processes and exit
• actual behavior
  Tests pass successfully, then it seems start-server-and-test stops the processes for the server (tested with both a webpack dev server started via a node script and also when the server is a simple http-server server called via a npm script), but suddenly the Error: server closed unexpectedly error is thrown. This doesn't happen when the npm script is run locally.

    ✔  All specs passed!                        00:08        6        6        -        -        -
