Image URLs that are split into arrays in metadata do not render in Nami wallet

I’m having issues with assets not rendering their images correctly which I believe is related to them being an array. The CIP for 721 metadata, it says image can be a URI or an array:

https://github.com/cardano-foundation/CIPs/blob/8b1f2f0900d81d6233e9805442c2b42aa1779d2d/CIP-NFTMetadataStandard.md

"image": <uri | array>,

My IPFS URLs are > 64 chars, so I split them into an array like this:

         image: [
            "ipfs://bafkreighf2nnlrg25yyf7u47gfgexj5jywzuyj6wlvp7uh2ofz2c2jqi",
            "g4"
         ],

However, they fail to render in nami wallet. If I inspect the page, I see that the URL being requested is like:

https://ipfs.blockfrost.dev/ipfs/bafkreighf2nnlrg25yyf7u47gfgexj5jywzuyj6wlvp7uh2ofz2c2jqi,g4

The comma near the end looks suspicious. It looks like this might have been fixed by b19439815d217247a001bb17884bfe0a90ade288 but that shipped in 1.1.3 and I’m using 1.1.5. I wonder if perhaps there’s another place that needs this - perhaps line 47 here? (I’m not sure of the difference between `result.metadata and result.on_chain_metadata):

Actually, I think this might be a Blockfrost issue:

}

            "cq"
         ],

I’ve sent Blockfrost an email to see if they agree and may fix this.

@1000101 yep, that looks correct to me too. My guess is CNFT.io isn’t handling images that are arrays of strings correctly then (and are just taking the first element).

I’ll follow up with them on their ticket. Thanks for your help!
