Problem

I think the problem is similar to this #382. But I found different case. I create minimal reproduce below. It's just simple scheduler using breejs. When I run tsx index.ts it will run the scheduler every 10 second just to console.log. Then this error is occured

Worker for job "hello script" had an error {
  err: ReferenceError [Error]: ___tsxInteropDynamicImport is not defined
      at [worker eval]:1:71
      at [worker eval]:1:126
      at Script.runInThisContext (node:vm:123:12)
      at Object.runInThisContext (node:vm:299:38)
      at node:internal/process/execution:82:21
      at [worker eval]-wrapper:6:24
      at runScript (node:internal/process/execution:81:62)
      at evalScript (node:internal/process/execution:103:10)
      at MessagePort.<anonymous> (node:internal/main/worker_thread:152:7)
      at [nodejs.internal.kHybridDispatch] (node:internal/event_target:757:20)
}

This error doesn't occure on tsx v3, and I can confirm that if you run the script without node:worker_threads, everything is work fine

// change this
const { workerData } = await import("node:worker_threads");
// to this
const workerData = {};

Expected behavior

Script run and scheduler will print the workerData in the console every 10 seconds

In this case, basically an eval is happening so it can't reach the closure reference. The same reason you had to dynamically import worker_threads inside path instead of at the top of the file. This issue is closer to #113.

You'll likely have to clear the cache or run with --no-cache to see it work.

Wow thanks for quick fix and your explanation. It's work now
