Minor nit.
Apart from that please squash commits before merging once you get approval from owners.

[arishta-yb]

Left minor comments, mostly around readability and adding safety checks. Also, squash all the commits before merging to keep the commit history clean :)

[bhupendray-yb]

I will resolve the comments.

Squash the commit

@bansal01yash @arishta-yb do I need to do it manually? In merge PR option I see, it's automatically going to squash and then merge.
