setState callback does not behave as expected, setState provide a callback to be called after the state changes,
and the callback is an action of redux:
addressInput = e => {
this.setState({
address: e.target.value
},
this.props.filterSearch(this.state.address));
}
I get this error
Warning: setState(...): Expected the last optional
callbackargument to be a function. Instead received: [object Promise].

- 1 You are calling the function there. Thus the return value is given as the second argument. – Dane Commented Oct 17, 2017 at 5:31

Reset to default 9It expect a "last optional callback argument to be a function".
Write it like this:
addressInput = e => {
this.setState({
address: e.target.value
},
() => this.props.filterSearch(this.state.address))
}
