I think this is a bug in ts-jest. If you follow the esm documentation it says:

Ensure that tsconfig has module with value for ESM, e.g. ES2015 or ES2020 etc...

If change your tsconfig to use those settings:

  "module": "ES2022",
  "moduleResolution": "Node",

Everything works fine. The error you are seeing comes from typescript using settings different than those in the tsconfig in the repo (running the build command/tsc works fine).

I'd recommend opening an issue with ts-jest, since this seems related to them changing or not respecting some options in the repos tsconfig. I personally don't use ts-jest, so not sure about next steps for debugging this further

Thanks so much for your help. It is working for me now.
