Hi I am new and an nft artist.
This forum was allready very helpfull pointing me to the right directions in my research, but now I am stuck as I am not familliar neither with the 721 contract (Meta, Json, Uri) nor code…
sorry if this problem has been discussed before, it is a litle hard for me to make sense of the information given here as it is on the complex side for e noob as me : )
I hope someone like @abcoathup might spare me a minute and light some wisedom on my problem.
Thank You !
I am investigating erc721 contract standards because I do have this problem:
- “collection” image/icon/cover doesnt show in coinbase wallet app (android).
while the single nft “collectibles” all work/show fine with their “covers”. the “cover” for the “collection” doesnt. I asume there is a broken link in the metadata pointing to wrong adress or maybe even no link/adress at all.
I checked on etherscan the query for “tokenURI” and got the error
" Error: Returned error: execution reverted: ERC721Metadata: URI query for nonexistent token"
Repeat, the NFTs inside the collection show and work fine, so it is only about the collection “cover”…
As I said I have no clue on this topic, so what does this mean and how to fix this?
thank you so much!
ps: I do have an er1155 “collection” working fine and gives “ipfs” sting without errors for the same query. This collection shows all fine in the wallet too!
