Different IPFS syntax on different NFTs from the same collection

[LoLoSenPai]

Hello guys. I tried to fetch all metadata from a Polygon collection (Brozo), and I saw they not all have the syntax for the IPFS URL. So I’m currently taking the token_id of each of these nfts and add it to the right url to fetch metadata.

Just to notice it

Hey @LoLoSenPai,

Not very sure what you mean, can you paste one of the token URL here so we can take a look?

Hi! Sorry for the slow answer ^^’

For example, this is the contract adress of Brozo on Polygon: 0x220fa5cCc9404802ED6DB0935EB4feeFC27C937e

If you try to use getNFTMetadata, you will see null metadata until token id 109 where the token_uri syntax is different.
For this one, there is metadata. So I had to make an algo to put on an array of null metadata objects, and change token_uri to add the missing metadata

And I had the same problem with Rekt Dogs collection on Polygon.
