Lesson 15 Duplicate NFT on Marketplace

[mitchhs12]

Hi! I have a problem when I try to update the price of my NFT using my front-end.
I'm not sure why but for some reason, I am getting a duplicate NFT (with the image).
When I check my local blockchain node it says

eth_call
  Contract call:       NftMarketplace#<unrecognized-selector>
  From:                0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266
  To:                  0x5fbdb2315678afecb367f032d93f642f64180aa3

  Error: Transaction reverted: function selector was not recognized and there's no fallback function

I have gone through my UpdateListingModal.js and I'm certain that my code is correct. What on earth could be causing this since the functionName I am calling in updateListingModal is "updateListing" and my contract definitely has the function "updateListing"?
Edit1: I should note, that my front-end is displaying the NFT with the same tokenID correctly, it's just not deleting the old one.|

Edit2: SOLVED, the site is updating the current NFT correctly (the problem was in my cloud functions) but my blockchain is still saying that the function selector is not recognized... why is this?

What happens when you git clone the repo and try things like that? That way you'll be 100% sure your code is the same.

If you do that, and still get an error, can you update this question with the exact steps you took?

I can't remember exactly what I did to fix this but I am pretty sure there was just a typo in my cloud functions.
