ERR_REQUIRE_ESM with jiti/register

[yshrsmz]

Environment

OS: Mac Sequoia 15.2
Node.js: 20.18.1
Package Manager: [email protected]
jiti: 2.4.2
TypeScript: 5.7.2
Fastify: 5.2.0

Reproduction

https://github.com/yshrsmz/jiti-watch-test

Describe the bug

When running Fastify app with node --import jiti/register src/index.ts, it throws an ERR_REQUIRE_ESM error.

I couldn't reproduce the error when I directly used thread-stream(it might be because I didn't fully understand thread-stream), so the repro has a bit big dependency.

Additional context

No response
