Hello⌠Me again⌠In the rarible clon my items show up, but the items for sale donât show and give this error 404 not found index.html:54

Is there supposed to be a URL in there?
Unsure if shortening for brevity or you have three â.â in there.

hi there, I have the same issue with you. Tried to read all related topics but did not find the answer yet.
this is the error message from console:
main.js:233 Uncaught (in promise) TypeError: Cannot set properties of undefined (setting âsrcâ)
at renderUserItem (main.js:233)
at main.js:283
Any admin willing to help? Thank you!
PS: I deployed both token and marketplace on Rinkeby and did change âEthNFTOwnersâ to âEthNFTOwnersâ in the cloud function.
Nobody nows yet
you can add there a console.log("item", item) before calling rederFunction(item) to see what you have
you could look in browser console to see if there are any errors, you could also print that tokenUri that it tries to fetch. this way you can get closer to the problem

it is solved!
the key is when you name the TableName on sync, it has to be the same as cloud function.
below is the sample for event itemAdded. do the same way for itemSold
