unable to run NFT Marketplace (coded earlier)

[PsychoPunkSage]

Hi,
I completed this course 3 months back.
At that time, the NFT Marketplace that I made using "TheGraph" was running perfectly, but now, for some reason, it is not running.
The website is working but I'm unable to see NFT owned by a particular account.

Backend + Frontend: https://github.com/APrakash-913/BlockChain---NFT-Marketplace
TheGraph: https://github.com/APrakash-913/graph-nft-marketplace

Please help me in this regard.

Not familiar with it but maybe this might help.

Check for errors: Check your server logs, console logs, and TheGraph's error logs to identify any errors that may be occurring. This can give you a good starting point to identify the issue.

Verify contract addresses: Make sure that the contract addresses for your NFTs are correct and have not changed since you last checked. If the contract addresses have changed, update them accordingly in your code.

Check TheGraph's subgraph: Verify that TheGraph's subgraph for your NFT marketplace is still running and is up-to-date. You can do this by checking the subgraph's version and ensuring that it is the latest version.

Verify API requests: Ensure that your API requests to TheGraph are being sent correctly and that the data returned by TheGraph is what you expect. You can do this by checking the network tab in your browser's developer console.

Verify smart contract interaction: Make sure that your smart contracts are interacting correctly with TheGraph. This includes verifying that the events emitted by your smart contracts are being captured correctly by TheGraph.

Check for updates: Check if there are any updates to TheGraph or any other dependencies used in your NFT marketplace. Updating these dependencies could potentially resolve the issue.
