Start-server-and-test "server closed unexpectedly"

Question

I'm using the start-server-and-test package to start a server on my Azure pipeline to run Cypress.

This is the yarn command I use to start everything: yarn cy:build:workspace

"cy:build:workspace": "yarn cy:clean && start-server-and-test start http://localhost:8080 cy:run:workspace"

I'm running NODE_VERSION: "12.10.0" on the Azure env.

"C:\windows\system32\cmd.exe" /D /E:ON /V:OFF /S /C "CALL "d:\a\_temp\ce28689e-eef6-4eeb-bad2-82310f748e1b.cmd""
yarn run v1.22.4
$ yarn cy:clean && start-server-and-test start http://localhost:3000 cy:run:workspace
$ rimraf cypress/reports/*
1: starting server using command "npm run start"
and when url "[ 'http://localhost:3000' ]" is responding with HTTP status code 200
running tests using command "npm run cy:run:workspace"

Locally I have everything running, any suggestions why the server stops on the Azure environment?

检查您的 package.json，如果您使用的是“react-scripts”：“3.4.1”降级到 3.4.0

还要验证此链接以将 start-server-and-test 与纱线一起使用，您需要像字符串一样添加一些纱线命令https://github.com/bahmutov/start-server-and-test#note-for-yarn-users
