Fail to set bool to false

[charles-liu]

pragma soliditypp ^0.8.0;
contract TestBool{

    mapping(address => bool) public adminMap;

    function setAdmin(address _addr, bool _state) external {
        adminMap[_addr] = _state;
    }
}

setAdmin(_addr, 0) won’t work.

Cause

It passes a string literal 'false' rather than a boolean literal false as the parameter to the ABI encoder.

How to fix

Convert the literal from string to boolean if the type of the parameter is bool.
