NFT not showing in marketplace, system management error "NFT 不存在"

[chuawh-theacemeta]

Minting is successful, it shows up in the smart contract and it is also pushed into the database. However, there are issues with retrieving the NFT information to be displayed in the vue-web marketplace. Also, when attempting to interact with the NFT authentication in the system management, there will be an error code "-1", "NFT 不存在".

NFT铸造完成后，需要一段时间让服务器与链上信息进行同步确认

I have let it run for awhile, however the NFT is still not showing up in the marketplace. I traced the source code and this is what I have found:

1. Looking at vue-web's /items route's view component, I see that it is attempting to retrieve NFT information from Springboot backend through the API call to /user/stat and /user/<collections | onsales | created | like. Doing a log of these calls gets me:

2. I understand in the database, there are NFTs existing. So I looked into fingernft-api source code. I found that the post mapping for /user/onsales triggers an fingernft-db's FcContractNftExtMapper.findOnsaleNft function. However, I could not investigate any further as FcContractNftExtMapper does not exist in the source code provided by fingernft-db:

3. I believe the problem lies on the connection between the Springboot backend and the smart contracts deployed on Rinkeby network. Do you have any idea of what could be causing the NFTs to not show up in the marketplace frontend? Could it be an ABI problem with the Springboot backend?

Also, how do I verify smart contracts that I have deployed through the System Management panel?

Thank you for your time.
