@helloanoop can you please check this when you get time, will this be the correct way to go about this ?

Hey, I just looked over your merge request, and it's not quite right.

You are using the headers from item.requestSent.headers but this is only set after sending a request.

The collection headers are stored in collection.root.request.headers and can be merged with the normal request headers. I added some code suggestion, with my idea.

@Its-treason thanks for the review. The only reason I wanted to stick with items was to make sure any new additions do not cause this piece to break again. But given that we only have collections for now, I think this is a good idea.
Thanks and please re-review

So I just saw this PR has been merged: #1316 that does the same thing as this PR.

So This PR might be obsolete, sorry I put you through the hassle of making review changes, I should have seen the other PR earlier
