[ETH] Metadata and token_uri null for ENS NFT

Technical Issue Reporting
#1

Hi,

I just found out that an ENS NFT is missing both metadata and token_uri.

token address: 0x57f1887a8bf19b14fc0df6fd9b2acc9af147ea85
token id: 2127920000458810003899342736271702203616657101742698003430585615846714349887

}

As you can see in the response, I even tried out resync metadata, which did not work as expected.
This is a well-known ENS contract address, no scam or anything.

I can fetch the metadata for the above NFT by visiting https://metadata.ens.domains/mainnet/0x57f1887a8bf19b14fc0df6fd9b2acc9af147ea85/2127920000458810003899342736271702203616657101742698003430585615846714349887/

Any help here? Thanks.

Hi, we will take a look, thanks for reporting.

#3

Hi @cryptokid, thanks for the help.

Is there any update from you guys?
This issue is causing our service to be unreliable when fetching NFT’s and relevant metadata from Moralis.

Thanks!

#4

ENS works different than the other nft standards. I sent your request to the team. I don’t have new updates yet.

#5

Hello, @cryptokid,

This issue is back for the same ENS and some other ENS as well.

What is exactly different for ENS compared to other NFT’s, and how can I garuntee those fields to be populated? resync does not seem to work.

#6

The difference is that ENS is not a standard NFT contract, and it has to be handled as a custom contract

#7

Understood,

So, I guess it takes for Moralis to handle it separately? because some ENS’s look fine and some do not.
But the first example ENS without metadata was minted a few months ago, so how do you guys handle ENS?

#8

We have a custom processing for it. I don’t know the exact details.

#9

So, for ENS, I cannot rely on Moralis for metadata / token_uri ?
:sob:

#10

It looks like you can get the token uri directly from token address and token id

Yes, but I did not want to add another dependency (rest call to another service).
But looks like this is the only viable solution now… thanks
