Greetings.
I have two fields - One for name and another for number. When submited it gets added to the "phonebook" in the mongoDB. Then it gets displayed in my list on the webpage. everything i have implemented: PUT,DELETE,GET requests, they work all very well, now i tried to implement the solution for UPDATING the number in my "phonebook" When the name is already in the list and we add a new number.
So, When the name matches but the number doesnt, this makes the Number for the name to update. Thus i am using PUT request for this along with findByIdAndUpdate(). But when i make the request, i receive no errors, network headers, success, fail or anything, as if i am not doing anything at all. Been trying to find out my problem but without any success for the past few hours.
