It was found that after removing package-lock.json and re-running npm i, now npm resolves TypeScript's version to a newer one which has a different module resolution behaviour with "moduleResolution": "NodeNext" in tsconfig.json.

Imports from sources without file extensions no longer work. e.g.,

TS2835: Relative import paths need explicit file extensions in ECMAScript imports when --moduleResolution is node16 or nodenext. Did you mean ./ decoders. js?
