I think both of the PRs having same code. OK, perfect to see the working /create-collection api 👍

In next PRs, are you targetting for get request of all projects & collections?

Actually both these PRs are raised around the same time, with similar code cause they are linked. This PR has some fixes for the concerned endpoint, createNewCollection

My next PR is including:
-an endpoint to remove the saved Projects from a collection, and
-fetch the saved projects inside the collection, implementing sorting ---
-By date added (newest → oldest, oldest → newest)
-By popularity (most liked → least liked)

I'm hoping this PR is up to the mark and no changes are required!!
Always open for feedback !!
