Directly linking typescript files without compilation breaks with wallabyjs

[bhvngt]

Issue description or question

Based on following this blog, I was trying to directly link my internal packages by changing the package.json exports as follows and removing the build step.

  "exports": {
    "./*": "./src/*.ts" // instead of "./dist/*.js"
  },
  "typesVersions": {
    "*": {
      "*": ["./src/*"] // instead of "./dist/*"
    }
  },

I am able to run my mocha test suite on the cli without any issue. My mocha config file is as follows

module.exports = {
	"node-option": [
		"experimental-specifier-resolution=node",
		"loader=esbuild-node-loader" // works with ts-node/esm also. I prefer esbuild-node-loader since it has built-in support for path alias.
	],
	"require": ["dotenv/config", "./tests/helpers/globalSetup.js", "chai/register-should"],
};

However, when I run the same test in wallaby, it throws following error.

Runtime error: TypeError [ERR_INVALID_MODULE_SPECIFIER]: Invalid module "file://./libs/store/src/SupabaseConnection.ts" 
    at new NodeError (node:internal/errors:371:5)
    at ESMLoader.load (node:internal/modules/esm/loader:324:13)
    at async ESMLoader.moduleProvider (node:internal/modules/esm/loader:230:47)

This error disappears if I reintroduce typescript compilation step for internal packages.

Direct linking simplifies my development time significantly as I can completely skip build time for internal packages. Any help here will be very much appreciated.

Can you please create a sample project repo with the working mocha setup (as you want it to work ideally) and we'll take a look to see how to configure the same thing in Wallaby? If you like, you may combine the sample repo with the other issue you've raised #2910.
