Using dynamic import of ESM library yields "Cannot find module"

[joaorodrigues-consensys]

Hi guys, we've got a statement in the code of a dynamic import of an ESM package:

const p = await import('@lodestar/params')

This code runs well at runtime (i.e.: application running) and the module is correctly imported.
However, it fails when running jest:

    src/app.controller.ts:9:28 - error TS2307: Cannot find module '@lodestar/params' or its corresponding type declarations.

    9     const p = await import('@lodestar/params')

Is there any settings I need to enable so that ts-jest imports the library correctly?

I've got a very simple repo to reproduce this issue. It's a plain nestjs project with a controller that dynamically imports the library:

• git repo: https://github.com/joaorodrigues-consensys/test-lodestart-libs
• offending line: https://github.com/joaorodrigues-consensys/test-lodestart-libs/blob/main/src/app.controller.ts#L9
• npm run start && curl http://localhost:6556 runs through controller code, loads the library and returns a valid value
• npm run test fails with Cannot find module '@lodestar/params' or its corresponding type declarations.
