Breakpoint not bound when Debugging Typescript Apollo Server (graphQL) in VS Code

Question

I am a java guy and new to nodejs. I am working on an existing typescript project. I am unable to debug my application. The break points are greyed out and shows "Breakpoint set but not yet bound"

Apollo Server (graphQL) listens on http://localhost:8080/RegisteredEndUserExtended

When launching the application it stops at a Breakpoint set in a config.ts file in the node_modules folder and when continuing, the application starts properly. When sending graphql requests, I get the response. But it doesn't stop at the breakpoints set in my.ts files (resolvers) in the src directory or.js files in the dist directory. I tried with VS code 1.51.1 also, but there is no luck. Please help.

Thanks in advance

Let's compare with my working configuration, maybe it helps you to understand what goes wrong (I see first difference that I launch TS-file in contrast to your launch of JS-file):

    {
      "type": "node",
      "request": "launch",
      "name": "Launch TS Program",
      "program": "${workspaceFolder}/app.ts",
      "env": {
        "NODE_ENV": "standalone"
      },
      "preLaunchTask": "tsc: build - tsconfig.json",
      "cwd": "${workspaceFolder}",
      "outFiles": [
        "${workspaceFolder}/build/**/*.js"
      ],
      "sourceMaps": true,
      "outputCapture": "std"
    },

and tsconfig.json

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "es6",
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "noImplicitAny": true,
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "sourceMap": true,
    "outDir": "build",
    "typeRoots": [
      "@types",
      "node_modules/@types"
    ]
  },
  "include": [
    "application/**/*",
    "@types/**/*",
    "app.ts"
  ]
}
