ERC20 allowance Moralis call

Hi, everyone! I seem to get a weird result when calling the ERC20 allowance function on Polygon for the address 0xFfeEcd85edF58666AEb95Cc2EFA855DA62E6ea56. The output is 49999999999999999957000000000000000000 wei which obviuosly can’t be true. I checked the result using Remix IDE and it returned 0. The other addresses seem fine.

Here is the code

export const _allowance = async(owner) => {
    let options = {
        chain: '0x89',
        address: '0x8f3Cf7ad23Cd3CaDbD9735AFf958023239c6A063',
        function_name: "allowance",
        abi: ERC20ABI,
        params: {
            owner,
            spender: '0xDfEc2EC7E96f54fD41B229122c30874e49c23a5F'
        },
    };
    try {
        let allowance = await Moralis.Web3API.native.runContractFunction(
            options
        );
        console.log('allowance', allowance);
        return allowance;
    } catch (error){
        console.error(error);
    }
}

Here ERC20ABI is imported from config. Thanks!

That amount you’re getting seems accurate, you can check the approve transactions made by the 0xFfeEcd85edF58666AEb95Cc2EFA855DA62E6ea56 address.
