Please post sample code - looks like a valid error.

Here is my current code, the issue that im having is that it works in editor & on desktop platform but when i build to webGL I recieve the error;

{ public async UniTask ExecuteMinting(string metadataUrl)

    long currentTime = DateTime.Now.Ticks;

    Debug.Log(currentTime);
    // Dummy TokenId based on current time
    _currentTokenId = new BigInteger(currentTime);

    object[] parameters = {
    _currentTokenId.ToString("x"), // This is the format the contract expects
    metadataUrl
};

    // Set gas estimate
    HexBigInteger value = new HexBigInteger(0);
    HexBigInteger gas = new HexBigInteger(0);
    HexBigInteger gasPrice = new HexBigInteger(0);

    string resp = await Moralis.ExecuteContractFunction(ContractAddress, ContractAbi, "mintItem", parameters, value, gas, gasPrice);

    return resp;
}

Okay I think we fixed an issue for this related with Nethereum which is where this is happening - are you using the latest version of the Unity Game Kit?

We also submitted an issue to the Nethereum team.

interestingly by removing some code and using a different smart contract (from elden ring tutorial) it works, although a few mintues delay when compared to desktop build;

    public async UniTask<string> ExecuteMinting(string metadataUrl)
    {

        object[] parameters = {
            metadataUrl
        };

        // Set gas estimate
        HexBigInteger value = new HexBigInteger(0);
        HexBigInteger gas = new HexBigInteger(0);
        HexBigInteger gasPrice = new HexBigInteger(0);

        string resp = await Moralis.ExecuteContractFunction(ContractAddress, ContractAbi, "getItem", parameters, value, gas, gasPrice);

        return resp;
    }
