Hi Manifold team, I really need your help with a technical issue on my marketplace listings.
-
What is your wallet address?

A summary of the issue:
The preview window for 8 of my marketplace listings is broken. However, the NFTs themselves, the token data, and the “Full Resolution” view all load perfectly for all of them. The underlying Arweave files are 100% healthy. The issue is exclusively with the 8 listing preview windows, which are failing to fetch from Alchemy’s CDN. -
What are you trying to do?
View my active listings on the Manifold marketplace. -
What is the actual outcome? Are you seeing any error messages?
Instead of loading the media in the preview window, all 8 affected listings display a JSON string like this:{"keyName":"8141c85dd887a95970e7afb9f18b681f_animation","partialUpload":true,"contentType":"text/html"}
Note: The keyName changes per token, but the partialUpload and contentType error is the same.
Here are the affected Listing IDs:
Rekindling - Derivative work - Private │ Not Secret collection - sarocha | Manifold

A screenshot of the issue/error with the console. Please find attached two screenshots:
- Image 1: The error displaying as raw JSON inside the iframe (the listing preview window).
- Image 2: The CORS error showing up in the browser console.
- The browser console shows a CORS error for all of them:
Access to fetch at 'https://nft2-cdn.alchemy.com/base-mainnet/8141c85dd887a95970e7afb9f18b681f_animation' from origin 'https://manifold.xyz' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
I have already tried “Refresh Metadata” and it did not fix them.
