VS Code Unverified Breakpoints

For anyone who runs into this error, I was able to find a solution. The issue was the way I was launching the Node process, not the mapping of the source maps (which produces a different error).

To attach to the process, I launched it from the VS Code terminal like this:

node --inspect dist/server.js

launch.json:

{
            "type": "node",
            "request": "attach",
            "name": "Attach by Process ID",
            "processId": "${command:PickProcess}",
            "protocol": "inspector",
            "address": "localhost",
            "port": 8080,
            "restart": true,
            "preLaunchTask": "npm: build",
            "sourceMaps": true,
            "outFiles" : [ "${workspaceRoot}/dist/**/*.js" ]
        },
