Any idea why my last NFT looks broken?

[Joro97]

So I have just submitted a solution to the final challenge of the course and got a NFT in my wallet in return, however its image looks like its broken. It does not display anything. The unction specialImage() external pure returns (string memory) returns a proper image. Can someone help me figure out if I misunderstood something in the challenge and if this is expected?
You could see my NFT on testnet OpenSea here. I have checked the collection and a few other NFT images seem to look like this as well.

Hello @Joro97, read this discussion Cyfrin/foundry-full-course-cu#2112 and this discussion from Foundry-full-course Cyfrin/foundry-full-course-cu#1289 it might be helpful.

Thanks for the threads. I have tried re-enabling all my NFT settings in MetaMask a few times and re-importing the NFT. Ran the tokenURI through a JSON formatter and it says the JSON is valid, however the NFT still shows blank. Pretty weird.

Weird indeed.
