(Tech request)Metadata missing on some wallet items when reading it from API

Let’s take this item for example, it got a perfect token id with it metadata but when I try to read it from the account/getNFTsForContract API from the swagger it return an null metadata for that item.

“symbol”: “ForestKnight”,
“token_uri”: “https://metadata.arkane.network/api/apps/5bacc710-7a34-4d30-b6d5-3808fe5a1685/contracts/137/tokens/0000000000000000000000000000000000000000000000000000000000000673/metadata”,
“metadata”: null

This need fix ASAP if possible.
