Thank you for finding this issue! I'm surprised that we haven't tested this case. Sorry, this library is fast-growing library, so there's still some rough-edges 🙏. I'll merge this after the workflows are passed.

@parasdaryanani I would be appreciated if you run yarn lint from the root of the project and commit the changes.
