vscode: Node JS debugging is inconsistent

Issue Type: Bug

When using the built-in debugger for Node JS scripts, I’ve noticed that the accuracy of the debugger in terms of line placement and breakpoints is extremely hit or miss in 1.2.5.0 (worked perfectly in 1.2.4). A few issues I’ve run into:

• With source maps enabled, the actual file opened in debugging will sometimes be wrong (if there are files in different directories with the same name, e.g., utils.js).

• Breakpoints will not respect the original line they were placed at, and will instead be indicated at a completely different location (even though the variables context is technically correct)

• Debugger statements will halt execution in the correct location, but the debugger itself will choose a random location in the file (or possibly a different file…see above).

Unfortunately, this isn’t 100% consistent; some files work as expected, others fail in one or two areas of the issues above, others are completely messed up. I’m not sure of the difference in the files, other than possibly collisions in files with the same name under different directories.

Here is the script I use to start my node script: "./node_modules/.bin/nodemon app/server.js --inspect --exec ./node_modules/.bin/babel-node"

And here is the launch config:

{
    "type": "node",
    "request": "attach",
    "name": "Debug",
    "processId": "${command:PickProcess}",
    "restart": true,
    "protocol": "inspector",
    "sourceMaps": false // tried both true and false
}

As I mentioned above, this configuration worked in 1.24, and the debuggin experience was superb. In 1.25.0, the debugging experience has significantly degraded, making it nearly unusable.

Please let me know if there is any other information I can provide to help facilitate a speedy fix for this. Thanks for this awesome product; hoping the debugging gets back up to snuff soon!
