Nodemon won't detect changes if I run it with npm run

I have the following command:

  "scripts": {
    "dev": "npx nodemon --watch 'src/**/*.ts' -e ts --exec ts-node --esm src/index.ts"
  },

If I run npm run dev nodemon will start successfully, but If I update any of my .ts files inside the src folder, nodemon won't detect changes in the project and won't re-run the project.

Nevertheless, If I run npx nodemon --watch 'src/**/*.ts' -e ts --exec ts-node --esm src/index.ts directly in my terminal, it will start successfully too, but this time it will actually detect changes in any of my .ts file in the src folder and re-run the project.

I have the following structure:

├───📁 .vscode/
│   └───📄 types.ts.code-snippets
├───📁 src/
│   ├───📁 entities/
│   │   └───...
│   ├───📁 resolvers/
│   │   └───...
│   └───📄 index.ts
├───📄 .gitignore
├───📄 backend-idea.yml
├───📄 package-lock.json
├───📄 package.json
└───📄 tsconfig.json

I tried to change 'src/**/*.ts' to "./src/**/*.ts" and it worked exactly like before.

What could be the reason it only works If I execute directly in my terminal and not with npm run dev? I am in Windows 11, Node v19.9, Powershell 7.3.6. (pwd is in the root directory of the project)

In order to make it work I had to replace the ' to \" & "\. So the script looks like that:

  "scripts": {
    "dev": "npx nodemon --watch \"src/**/*.ts\" -e ts --exec ts-node --esm src/index.ts"
  },
