Error handling in react redux with useSelector hook

developersatyajit — Thu, 12 Nov 2020 06:11:53 +0000

I am using useSelector hook in my UI. But I can not handle the error that is coming form the API. I can see the reducer is getting updated with the error in my redux state. When I am going to show this error in UI, its not showing. The submit button is in the Modal popup.
Like below:

UI ----

const dispatch = useDispatch();

const {error} = useSelector((state) => {
error: state.error
})

const handleModalSubmit = () => {
dispatch(myReducerFunction())
// here I wan to catch the error like which is not working.
if(error) {
// this error is showing as null or the previous redux state not the updated one which is coming from the reducer
}
}
