[Ethereum] How to fix Error: invalid address

contract-debuggingerrormetamaskremix

I am trying to run the smart contract listed in the documentation here https://docs.soliditylang.org/en/v0.8.7/introduction-to-smart-contracts.html#subcurrency-example

    // Sends an amount of newly created coins to an address
    // Can only be called by the contract creator
    function mint(address receiver, uint amount) public {
        require(msg.sender == minter);
        balances[receiver] += amount;
    }

But every time I try to execute the mint function, it fails with the following error:

transact to Coin.mint errored: Error encoding arguments: Error:
invalid address (argument="address", value="1000000",
code=INVALID_ARGUMENT, version=address/5.4.0) (argument=null,
value="1000000", code=INVALID_ARGUMENT, version=abi/5.4.0)

I am using the Remix IDE integrated with my MetaMask.

Any idea why and how to fix it?

As per the error message and logs it looks like you're passing invalid arguments ---

(argument="address", value="1000000", code=INVALID_ARGUMENT, version=address/5.4.0)

The address argument expects an address type argument, but you're passing a number (1000000) instead.

(argument=null, value="1000000", code=INVALID_ARGUMENT, version=abi/5.4.0)

The second parameter should have had an argument type "amount" but it appears to be null.

Looks like you need to double-check the parameter-argument pairs that you're passing.
