It seems that if we try to use the V8 stack trace API to get an array of structured CallSite objects when using ts-node, those objects don't have the correct line numbers or columns on them.
This project is an attempt to make a minimal reproducible example.
To reproduce, clone the repo, then:
npm install
npm run start:ts
You should see:
➜ stacktrace-test npm run start:ts
> [email protected] start:ts
> ts-node src/index.ts

Notice how the line numbers in the prepareStackTrace output are wrong - 13 and 15 when they should be 16 and 19.
