CAUSED_BYRootCause

The Reactotron Redux integration is being used incorrectly as middleware/without attaching the expected store/enhancer, so reactotronRedux receives an undefined store during initialization.

State Management

FIXED_BYSolution

Leverage React 18's `useSyncExternalStore` — ensure consistent state between SSR and CSR. Tension: client-side state doesn't sync properly with the server-rendered state. Outcome: to ensure consistent state between SSR and CSR.

FIXED_BYSolution

Initialize and return the state from the store initializer with `windowSize: window.innerWidth`, and only register the resize listener (cleanup is handled by React, not by returning `removeEventListener` from the `create` function).

FIXED_BYSolution

Use get() inside the store creator to read current state, and call useCart.getState() only on the store hook instance

FIXED_BYSolution

Properly mock the Zustand store module by spying on/overriding the store export (the Zustand `create` result or the correct store factory export) to return a custom state and action implementation, then render the component and assert against the mocked behavior.

FIXED_BYSolution

change your import from — import { getState, setState } from './stateStorage';.

FIXED_BYSolution

Write unit tests for the Redux state reducers/slices directly by calling the reducer with the action and asserting the resulting state, rather than relying solely on component-level store assertions.

FIXED_BYSolution

Add Reactotron using it as a store enhancer (e.g., via store `enhancers: [Reactotron.createEnhancer()]`) and ensure it’s configured/used with the Redux store instance before calling `.connect()`.

FIXED_BYSolution

Store only the primitive/client construction parameters (e.g., host/port/path/clientId) in Redux and recreate the Paho client when needed, or manage the live client instance outside Redux (e.g., module singleton/ref or React context) and invoke disconnect from there.

FIXED_BYSolution

Tension: cannot itself access any Redux context because none is provided to it from higher up the ReactTree. Outcome: so it can access the provided Redux context.

FIXED_BYSolution

Install the Redux DevTools browser extension and rerun the app so `composeWithDevTools` can work correctly.

FIXED_BYSolution

Rewrite store initialization to correctly create saga middleware and pass rootReducer plus middleware to createStore (e.g., use sagaMiddleware.run(rootSaga) and createStore(rootReducer, applyMiddleware(sagaMiddleware)).

FIXED_BYSolution

access the current state value via `store.getState` — within the submit handler. Tension: the callback can't possibly see any updated selected state values from outside the closure scope. Outcome: console.log(store.getState().loginReducer.success).
