I CLONED RARIBLE IN 24H - Reselling tokens[PART 15]

Moralis General
#1

Really enjoying this tuorial but I seem to be experiencing a UX issue. Whenever, I buy an NFT from the marketplace , the listed NFT disappear and goes to ‘My items’ section as it should do. However, after refreshing the page the bought NFT does not appear in the ‘My Items’ list anymore. The NFT gets delisted from the marketplace but it still appears in the Sellers ‘My Item List’ eventhough the ERC721 token has been transfered over.

The only way the NFT seems to appear back in the buyers ‘My Items’ List is when the NFT seller logs in and makes any transaction.

Im really confused what could be causing some help would be appreciated.

At a first look is sounds like some data was not updated in Moralis server db.
You could check what database updates should happen, and see if those updates happened in database.

#3

How can I check this?

#4

you could look in the code, see in what database table data should go, as in the table where from it reads that data to display it in the interface, and check if the data made it there, or in what step it doesn’t work
