@subhod-i I tested the scenario and PR #22804 appears to have addressed the issue. Will continue working on getting it merged.

webpack@4 has a quirk, but it is doable to fix this on the side of your package, e.g. using mjs extension or adding "type": "module" to package.json

@davidyuk I added "type": "module" in PR #22804. However, the repro project now gives another error as mentioned above. I am still trying to figure out whether there’s anything I can do to fix that.
