Released in v4.7.2!

Thanks for your contribution @cenfun 🙌!

@privatenumber I create a new PR here https://github.com/privatenumber/tsx/pull/518 Could you please review it?

It seems that the root cause is because inline sourcemap no longer works in nodejs 20.12.0. VSCode debug might not work if there is no inline sourcemap.

Hope this helps you.

Thanks @tenpaMk2

Would you or @piquark6046 be willing to investigate this?

I’m not personally affected by this so I’m unlikely to work on it unless paid to.

I can confirm this behavior, and I’ll add that I can also reproduce with the tsx smoketests in 20.12. If @cenfun isn’t submitting a PR for this, I’d be happy to - I’ve invested time already wrapping my head around this bit of code and I have a workaround by pinning my environment to node 20.11

Paid 15 USD.

@privatenumber VS Code breakpoint works with Node.js 18.20.0. However, it does NOT work with Node.js 20.12.0. (Tested with tsx-vscode-debug-not-working on Dev Container)

Please take a look. I think that it is a major bug of your tsx package.
