Missing metadata (animation and animation_url) when minting HTML on Sepolia

Bug Reports
1

Hello,

I’ve deployed a new ERC-721 contract to Sepolia successfully, but when I create a token with HTML artwork and an SVG thumbnail, then mint to Sepolia, the metadata excludes the animation and animation_url properties that I’d expect to see based on previous mints.

Is this a Sepolia-only issue, or should I expect that the same issue would occur when minting to Mainnet?

Another issue I’ve encountered with Manifold Gallery on Sepolia at least: the image source is broken with c_limit,q_80,w_1024/ appearing before https, where I’d expect to see the artwork at the top of the page.

I took a chance and deployed the contract and minted the token to mainnet, and the animation and animation_url properties are in the metadata as originally expected, despite them not appearing on Sepolia.

Manifold Gallery displays the artwork as intended too.

It would be great to have confidence that tokens minted with Manifold on Sepolia are as close to a 1:1 representation of Mainnet as possible.

Thanks for the report. I can’t seem to reproduce the c_limit,q_80,w_1024 on sepolia issue. Are you still seeing it? maybe a bad cached version of the widget?

If you clear your cache, does your sepolia gallery link still show this issue?

Thanks wilkins.eth — clearing cache appears to solve the Sepolia Gallery issue.
