Lesson:14 call revert exception; VM Exception while processing transaction

[Shawon-Mandal]

I follwed the tutorial video and got this error: Error: call revert exception; VM Exception while processing transaction: reverted with reason string "URI Query for nonexistent token" [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ] (method="tokenURI(uint256)", data="0x08c379a00000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000001f55524920517565727920666f72206e6f6e6578697374656e7420746f6b656e00", errorArgs=["URI Query for nonexistent token"], errorName="Error", errorSignature="Error(string)", reason="URI Query for nonexistent token", code=CALL_EXCEPTION, version=abi/5.7.0)

Can you leave a repo link please.

Also spell check your contract at this function:

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

@Shawon-Mandal This is the issue due to the invalid token Id because while minting you are updating the token id first and then minting an NFT due to that your first NFT index starts at 1 but in the mint file you are accessing at index 0.

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

You should update it after _safeMint.
