Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. — Community

As the error suggests

state.productDetails is not a function

This is because productDetails is a reducer object and Not a function created by redux. Hence, your code should be

const { loading, error, product } = useSelector((state) =>state.productDetails); //Note: productDetails without '()'

Hope it helps.

Side Note: While posting any question or answer please format the code properly next time so it's readable. :)
