Moralis API can't find meta data

Question

I'm attempting to retrieve metadata from these NFTs using the Moralis APIs. So far I'm partially successfull with the API enpoint https://deep-index.moralis.io/api/v2/nft/{address}/{ID}?chain=matic&format=decimal I'm able to get the data for any NFT with an ID of 1 - 670. Any NFT with an ID higher than 671 gives the response { "message": "No metadata found! Try again later" }

After attempting a bit on my own I asked the question on the moralis forum. They advised me to re-sync the metadata / uri, which I did using the API https://deep-index.moralis.io/api/v2/nft/{address}/{ID}/metadata/resync?chain=matic&flag=uri&mode=sync. This gives the response { "status": "The metadata could not be updated! Try again later" } testing the API to grab the meta data again confirms that nothing was changed.

Any solutions to this issue or alternative ways to get the metadata are welcome.
