Describe the Bug

I encountered an issue with express-openapi when using it in conjunction with the pkg, like: pkg . --no-bytecode --public-packages "*" --public. The issue arises when express-openapi tries to dynamically import modules using import with the file:// protocol in a bundled environment, like: const imported = await import(`file://${fsRoutesItem.path}`). It seems that the library is attempting to load modules from the local filesystem rather than from within the bundled package.

I understand that this may be a known issue, but I'm sharing it here in case anyone else encounters a similar problem with the library. I also want to provide a temporary solution that worked for me.

Solution: I was able to resolve this issue by manually patching the await import line in my package.json configuration, like so:

 "pkg": {
    "scripts": [
      "build/**/*.js"
    ],
    "patches": {
      "./node_modules/openapi-framework/dist/index.js": [
        "const imported = await import(`file://${fsRoutesItem.path}`);",
        "const imported = require(fsRoutesItem.path);"
      ]
    },
    "targets": [
      "node16-linux-x64"
    ]
  }

Expected Behavior

In a bundled environment, express-openapi should correctly load modules from within the bundled package, rather than attempting to load them from the local filesystem.

To Reproduce

1. Create a Node.js application that uses express-openapi and pass the paths to it, like:

   initialize({
   app,
   paths: path.join(__dirname, '../build/api/routes'),
   });

2. Bundle the application using the pkg utility.
3. Run the bundled application.
4. Observe that express-openapi attempts to load modules from the local filesystem instead of the bundled package.
