javascript - VS Code: "Breakpoint ignored because generated code not found" error

Question

I have looked everywhere and I still have issue debugging TypeScript inside VS Code. I have read this thread but still I am not able to hit my breakpoints placed inside a TypeScript file, hitting the breakpoints in .js files all works fine.

So here is the simplest "hello world" project I have set up.

• app.ts:

  var message: string = "Hello World";
  
  console.log(message);
  

• tsconfig.json

  {
      "compilerOptions": {
          "target": "es5",
          "sourceMap": true
      }
  }
  

• launch.json

  {
      "version": "0.2.0",
      "configurations": [
          {
              "name": "Launch",
              "type": "node",
              "request": "launch",
              "program": "${workspaceRoot}/app.js",
              "stopOnEntry": false,
              "args": [],
              "cwd": "${workspaceRoot}",
              "preLaunchTask": null,
              "runtimeExecutable": null,
              "runtimeArgs": [
                  "--nolazy"
              ],
              "env": {
                  "NODE_ENV": "development"
              },
              "externalConsole": false,
              "sourceMaps": true,
              "outDir": null
          }
      ]
  }
  

I have generated the js.map files by running the tsc --sourcemap app.ts command.

After all of those steps when I set a breakpoint on the console.log(message); row and launch the program (F5) from the "Debug" tab that breakpoint is grayed out saying "Breakpoint ignored because generated code not found (source map problem?)." I attached a screenshot of what I am observing:

What am I missing?

Edit:

Hi, I am still stuck on this. I managed to make one sample project that was hitting the break points but after I tried to copy that project to a different location on my HDD the break points again became gray and were not hit. What I did different in this test project was to use inline sourcemaps by compiling the TypeScript files with tsc app.ts --inlinesourcemap

I uploaded the mentioned sample project to GitHub so you can take a look at it here.

Setting "outFiles" : ["${workspaceRoot}/compiled/**/*.js"] solved the issue for me.

"outFiles" value should match one set in tsconfig.json for outDir and mapRoot which is ${workspaceRoot} in your case, so try "outFiles": "${workspaceRoot}/**/*.js"

Here are my tsconfig.json

{
    "compilerOptions": {
        "module": "commonjs",
        "noImplicitAny": true,
        "removeComments": true,
        "preserveConstEnums": true,
        "sourceMap": true,
        "target": "es6",
        "outFiles": ["${workspaceRoot}/compiled/**/*.js"],
        "mapRoot": "compiled"
    },
    "include": [
        "app/**/*",
        "typings/index.d.ts"
    ],
    "exclude": [
        "node_modules",
        "**/*.spec.ts"
    ]
}

and launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "program": "${workspaceRoot}/compiled/app.js",
            "cwd": "${workspaceRoot}",
            "outDir": "${workspaceRoot}/compiled",
            "sourceMaps": true
        }
    ]
}
