@abdullahtanvir11 The issue is clearly mentioned in your error if you try to read it you can easily understand the problem. It says execution reverted: URI Query for the nonexistent token which means the token you are looking for does not exist.

Because you are looking to token id 0 here;

console.log(`Dynamic SVG NFT index 0 tokenURI: ${await dynamicSvgNft.tokenURI(0)}`)

but you minted the token for token id 1

function mintNft(int256 highValue) public {
    s_tokenIdToHighValues[s_tokenCounter] = highValue;
    s_tokenCounter += 1;
    _safeMint(msg.sender, s_tokenCounter);
    emit CreatedNFT(s_tokenCounter, highValue);
}

Here you first increment the token counter and then you mint the token with an incremented token counter which is 1.

If you want to start from token Id 0, then you should increment this counter variable after mint.
