Hi @salaryhero-anh , thank you for logging this issue. We are in the final stages of development of our new NodeJS agent, which is hosted in this repo: https://github.com/getappmap/appmap-node

If possible, could you check if your issue exists with this new agent instead? We would also just love your feedback on it. It already supports Express.js and Node 18. You can try it with npx appmap-node@latest <command>.

Thank you!

[salaryhero-anh]

Cool @brikelly will check this out

Hi @brikelly, dose this support project using babel?

[brikelly]

Hi @salaryhero-anh - Babel should be fine, assuming it's just used for transpiling code. The new Node agent maps JavaScript code regardless of how it came to be :)
