Hi @Daxesh Thoriya , thank you for submitting.
We use Microsoft Q&A to answer questions, and it looks like you're reporting a bug. We use GitHub issues to track bugs. Our GitHub issues have a system for tracking information about your operating system and application build number, and a set of questions for you to answer while submitting the bug. Microsoft Q&A doesn't offer the tracking system we need to help resolve your bug.
Please submit this issue as a bug to the office-js repository on GitHub: https://github.com/OfficeDev/office-js/issues
Thanks,
Alison
