Unexpected early exit (code 13) when trying to import {} from a dynamic import()

[brianjenkins94]

This is a weird one where I could just be doing something stupid, but I'm reasonably certain this is code that has worked for me in the past.

I've run into the exit code 13 problem before but it turned out to be a conditional logic issue where I wasn't returning anything.

For reference:

13 Unfinished Top-Level Await: await was used outside of a function in the top-level code, but the passed Promise never resolved.

exit code 13, dynamic import

Expected Behavior

The BASE_URL gets console.logd.

Actual Behavior

Unexpected early exit (code 13) on the dynamic import().

Steps to reproduce the problem

node --experimental-specifier-resolution=node --loader=ts-node/esm server.ts

Minimal reproduction

// server.ts
import * as path from "path";
import * as url from "url";

const __filename = url.fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);

export const BASE_URL = new URL("http://localhost:8080");

const exports = await import(url.pathToFileURL(path.join(__dirname, "index.ts")).toString());

console.log(exports); // <-- we never get here

// index.ts

// The error appears to be contingent on this import:
import { BASE_URL } from "./server";

export async function get(request, response) {
	console.log(BASE_URL);
}

I've tried on Windows (21H2) and Linux via a devcontainer (Linux docker-desktop 5.10.16.3-microsoft-standard-WSL2), same results.

cspotcode helped me on Discord to determine that the same results happen without ts-node at all.
