The same endpoint was working yesterday but suddenly has stopped working today .

try to log that value, it looks like the value is undefined based on that error

#4

this is the value? this is where it tries to do that value.toUpperCase()?

#5

Will need to go inside the module for logging that value

#6

value.toUpperCase() is part of the error

#7

Made the edit please check

#8

ok, I think that I understand now what is the issue

Thank you for the assistance, the issue seems persistent

#10

you could filter the results by this token address if you want a quick fix, in case that you don’t want the first nft

#11

We will need all the NFT’s and it’s metadata @cryptokid. The endpoint was working yesterday with the same nfts . Can you please confirm what went wrong ? I will patch it with your fix or something else till then .

#12

what is seems to be wrong is that somehow first nft doesn’t have a contract type associated and it crashes when it tries to read the contract_type for that nft

alternatively you can read the raw data directly by making REST http requests to deep-index url as another possible work around, the data that you pasted above

#13

you can try again now to see if it works

#14

It’s working. Thank you
