Broken Listing Previews for 8 tokens - Alchemy CDN Cache Error (partialUpload: true, contentType: text/html)

Hi Manifold team, I really need your help with a technical issue on my marketplace listings.

  • What is your wallet address?
    0xe8af5f8338ea2a9778c899b42c311388035b4c05

  • 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
    AND @sarocha/id/:
    4038332656
    4038338800
    4038342896
    4038340848
    4038377712
    4038383856
    4038381808

  • 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.

  • What browser are you using?
    Brave, Google Chrome, Avast and Firefox (Desktop), and Brave and Chrome for Android.

  • What wallet are you using?
    MetaMask

Thanks in advance for your help!

Best regards,
