[Testing] This code explicitly handles modules not being found, unknown file extensions, and unsupported ESM directory import errors. For each of those three codes, could you please either reply with the existing test or add a new one? I just want to make sure we're on the same page of what test coverage there is.

[Testing] Why remove the
