Hello @olehmisar.

Please provide a minimal reproduction using StackBlitz, TypeScript Playground (for type issues), or a separate minimal GitHub repository.

Minimal reproductions are required as they save us a lot of time reproducing your config/environment and issue, and allow us to help you faster.

Once a minimal reproduction is added, a team member will confirm it works, then re-open the issue.
