Uncaught TypeError: useContext(...) is undefined
Solution 1:
I think the issue is with useRouteMatch which requires the Router context (which in your case is defined in the same component and therefore not accessible).
Instead of useRouteMatch try the following:
<Switch>
<Route path="/">
<Home />
</Route>
<Route path="/about">
<About />
</Route>
<Route path="/users">
<Users />
</Route>
</Switch>
