Error in adding concurrently in package.json

Question

scripts in package.json

"scripts": {
    "start": "node back-end/server.js",
    "server": "nodemon back-end/server.js",
    "client": "npm start --prefix front-end",
    "dev": "concurrently \"npm run server\" \"npm run client\"",
    "test": "echo \"Error: no test specified\" && exit 1"
  },

whenever I run the code using concurrently it shows me error like this

$ npm run dev

> concurrently "npm run server" "npm run client"

[0] Error occurred when executing command: npm run server

Which of these [Q&A search results](//google.com/search?q=site%3Astackoverflow.com+node+spawn+cmd.exe+ENOENT) have you read and tried? — Sebastian Simon, Jun 19 '21 at 06:17

Try by replacing "dev": "concurrently \"npm run server\" \"npm run client\"", with

"dev": "npm run server && npm run client",
