Don’t error on the new "error" type in Solidity ABI

[ricmoo]

Solidity has added a new "error" type and the current parser will throw if unknown types are included.

I just need to add '"error"` to the whitelist of fields to ignore in a patch version.

Support for the EIP-838 errors will be added in the next minor version.

This should be fixed in [5.1.4])https://github.com/ethers-io/ethers.js/releases/tag/v5.1.4). Try it out and let me know. :)

I still have the error on 5.1.4.
I'm trying to compile the contract using hardhat.

Here is the error :

Error: invalid fragment object (argument="value", value={"inputs":[{"internalType":"uint256","name":"available","type":"uint256"},{"internalType":"uint256","name":"required","type":"uint256"}],"name":"InsufficientBalance","type":"error"}, code=INVALID_ARGUMENT, version=abi/5.1.1)

  argument: 'value',
  value: {
    inputs: [ [Object], [Object] ],
    name: 'InsufficientBalance',
    type: 'error'
  }
}

Here is the code that raises that error :

    error InsufficientBalance(uint256 available, uint256 requested);

    constructor() {
        minter = msg.sender;
    }

    function mint(address receiver, uint amount) public {
        require(msg.sender == minter);
        require(amount < 1e60);
        balances[receiver] += amount;
    }

    function send(address receiver, uint amount) public {
        if (amount > balances[msg.sender])
            revert InsufficientBalance({
                available: balances[msg.sender],
                requested: amount
            });

        balances[msg.sender] -= amount;
        balances[receiver] += amount;
        emit Sent(msg.sender, receiver, amount);
    }

I'm not sure what to provide so feel free to ask me more information :)

Edit : It works for you and fragio so i must do something wrong

I did a fresh install and it seems to work !
