Dynamic imports not resolved correctly

[late-warrior]

What version of Bun is running?

1.0.6+969da088f5db3258a803ec186012e30f992829b4

What platform is your computer?

Darwin 23.0.0 arm64 arm

What steps can reproduce the bug?

A dynamic import in code like below (trial/components) is not resolved correctly in the output bundle -

import React, { lazy } from "react";
import ReactDOM from "react-dom";

console.log("entrypoint");
const Components = lazy(() => import("./trial/components"));

function App() {
  return (
    <React.Suspense fallback={<span> Loading </span>}>
      <Components />
    </React.Suspense>
  );
}

ReactDOM.render(<App />, document.querySelector("#root"));

• Build command run - bun build --splitting --outdir=static ./src/index.js

Complete reproducer in https://github.com/late-warrior/bun-dyn-import-bug.

What is the expected behavior?

• In the built output file (static/index.js) -

// Seen
var Components = import_react.lazy(() => import("trial/components.js"));
// Expected
var Components = import_react.lazy(() => import("./trial/components.js"));

What do you see instead?

No response

Additional information

Tried setting a few options like --public-path and also varying the location of the entry point to see if that has an effect but could not figure out.

Same here, but I'm using FileSystemRouter from Bun.

const router = new Bun.FileSystemRouter({
  style: 'nextjs',
  dir: './server/endpoints'
});

Bun.serve({
  port: Settings.server.port,
  hostname: Settings.server.hostname,
  development: true,
  async fetch(req, server) {
    const url = new URL(req.url);
    const path = url.pathname;

    const match = router.match(path);
    if(!match) return Utils.jsonResponse(Errors.getJson(404), 404);

    const { src } = match;

    try{
      const module = await import('./endpoints/' + src);
      return await module.default(req, match);
    }catch{
      return Utils.jsonResponse(Errors.getJson(404), 404);
    }
  }
});

Works great with bun run server/index.ts, but it doesn't work after I bundle it with: bun build server/index.ts --compile --minify --outfile ./rabbitchat
