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

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
        }
    ]
}

Here is small project, where you may see all parameters set https://github.com/v-andrew/ts-template


I came across this question while looking for a solution to a similar problem that I was having. Despite being different from OP's problem, it might help others.

Context: I was following the Visual Studio Code HelloWorld example and found myself unable to stop on break points.

I solved my problem by changing .vscode/launch.json so that "sourceMaps": true attribute under the Launch configuration was set (it starts default on false).
