How to clear error message coming from redux actions

I have an API, which may return an error. In the simplistic form, the component reads as below. The question is, when an error occurs, what is the steps to dismiss/clear the error message?

class LoginError extends Component {
    render() {
        return (
            {
                this.props.error != null ?
                    <h2>this.props.error</h2> :
                    undefined
            }
        )
    }
}

const mapStateToProps = (state) => {
    return {
        error: state.error
    };
}


export default connect(mapStateToProps, null)(LoginError);
