Could you describe a bit more about which issue you're trying to solve?

Issue is similar to this one vercel/ncc#480
Compiled code can't resolve module without extension when using dynamic imports.

I have signed Contributor Agreement. Should I do it again?

[vitramir]

Is commit message ok now?

[watson]

The commit message looks fine, thank you 👍

Regarding the CLA: I can see that you signed with a different e-mail than the one you used in the git-commit (the one in the git-commit ends with @icedigital.ru). That's why the CLA-checker isn't happy. You either need to use a different e-mail in the commit or sign again using the e-mail ending with @icedigital.ru. Sorry for all the trouble.

[vitramir]

I have submitted new CLA
