Problem reading module.parent.filename when using commonjs

While running the app locally (npm run dev) - everything is fine. Package.json below:

    ],
    "watch": [
      "src"
    ],
    "exec": "npm start",
    "ext": "ts"
  }
}

Tsconfig.json:

{
    "compilerOptions": {
        "module": "commonjs",
        "esModuleInterop": true,
        "target": "es5",

            "*": [
                "node_modules/*"
            ]
        }
    },
    "include": [
        "src/**/*"
    ]
}

The problem occurs when I build production app. When trying to launch the server by calling "node index.js" - I'm getting error:

Error: Could not find package.json up from 53263

By digging some source code I found this line of code in index.js of prometheus-api-metrics:

require('pkginfo')(metricsMiddleware, { dir: Path.dirname(module.parent.filename), include: ['name', 'version'] });

Apparently, when using "commonjs" - module.parent does not exist and it is causing a problem.

Does anyone have any solution for this?
