Redux Action Integration Mismatches

redux-integration-mismatch

Redux Toolkit state updates fail because dispatched action types, slice-generated action names, and listener/middleware registrations don’t align; as a result, reducers never run, fulfilled mutations never merge, and DevTools can’t attribute actions reliably.

MATCHESSolution

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.

MATCHESSolution

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.

MATCHESSolution

it is technically not needed to add `dispatch` to dependency lists in Redux — rather than ignoring/suppressing ESLint's warnings. Tension: it is still a much better practice to include it anyway. Outcome: always follow what the ESLint rule says.

MATCHESSolution

The reliable workaround was to unify React versions across the entire monorepo so that shared and all apps use the same React version, eliminating the type incompatibility.

MATCHESSolution

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.

MATCHESSolution

Create a separate slice that updates history via `extraReducers` using `api.endpoints.<endpoint>.matchFulfilled` (e.g., push `action.payload` into history). Alternatively, dispatch a normal Redux action when the query is fulfilled (via query lifecycle hooks or other middleware-like dispatch) to store the data.

MATCHESSolution

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()`.

MATCHESSolution

Move the `router.post` logout call and `onFinish` handling into an async action (e.g., `createAsyncThunk`), then update `isLogouting`/`isOpeLogoutDialogue` in the slice via `extraReducers` on pending/fulfilled/rejected to ensure the flags are reset.

MATCHESSolution

Align the state interface with the real thunk payload types (use `Goal[]` instead of `[]`) and explicitly type/cast the thunk `fulfilled` payload and the reducer `action` (including casting `action.error` to `string`).

MATCHESSolution

Update the `editTodo` reducer to always return a value in the `map()` callback (return the original `todo` for non-matches), or mutate the found todo directly using Immer without returning `undefined` elements.

MATCHESSolution

Fix the reducer to use only one approach: either mutate the draft without returning a new value (e.g., remove the `return` or use `void`), or avoid mutation and return a fully new state array from `map`.

MATCHESSolution

you need to use the specific customized `AppDispatch` type from the store — For `useDispatch`, the default `Dispatch` type does not know about thunks. Outcome: Update your `src/Client/RedGranite.Client.Web/src/app/hooks.ts` file to the current suggestion.

MATCHESSolution

Update the selector to read from the correct key, e.g. useSelector((state) => state.fileUpload.files), or change the store reducer key to match the selector.

MATCHESSolution

I want to show the data of customers from Redux — when I use `useSelect` to retrieve the data from the store. Tension: entries.map is not a function. Outcome: retrieve the data from the store.

MATCHESSolution

Dispatch actions using the correct namespaced `type`, e.g. `dispatch({ type: `transactions/${action}`, amount })`, or ensure `action` already includes the `transactions/` prefix.

MATCHESSolution

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.

MATCHESSolution

You are not allowed in Redux, ever, to dispatch from inside a reducer. — Reducer logic has to be a pure synchronous function without side effects. Tension: You might want to do the logic you are currently doing in a thunk or with the listener middleware instead. Outcome: You have to use `createAsyncThunk` for that.

MATCHESSolution

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

MATCHESSolution

An async function was passed to useActionState.

MATCHESSolution

Redux-Toolkit also ships with Thunk middleware included and enabled by default — If you needed to configure and/or add middleware, use the `getDefaultMiddleware` utility.

MATCHESSolution

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)).

MATCHESSolution

const user = useSelector(state => state.auth.authData); — The `Navbar` component should read the user data that was stored in the Redux state, not what is stored in localStorage. Tension: Updates to localStorage don't trigger React to rerender. Outcome: dispatch(logoutAuth());.

MATCHESSolution

resolve npm install @reduxjs/toolkit@^1.9.6 — in my Expo project. Tension: createSlice is not a function (it is undefined). Outcome: npm install @reduxjs/toolkit@^1.9.6.

MATCHESSolution

Move the `Auth()` invocation into a thunk action (or call it from the component) and have the reducer handle only state updates based on the thunk’s dispatched success/failure actions.

MATCHESSolution

Stop using `nativeEvent.path` in the action payload. Dispatch explicit values instead (e.g., pass the trait `id` and input value directly in `payload` from the UI) and update the reducer based on those fields.

MATCHESSolution

Use the reducer exported by createSlice in configureStore; the store gets the initial state from that reducer

MATCHESSolution

Update the reducer logic to access into `action.payload.applicationUser` property. — Redux-Toolkit slice reducers. Tension: the reducer is accessing some `user` property that doesn't exist in the response object. Outcome: Mutate state directly.

MATCHESSolution

Add extraReducers/addMatchers for each mutation endpoint (addTour, editTour, removeTour) to update `state.tour` on `matchFulfilled`, or use RTK Query tags and invalidation so queries refetch and state stays in sync.

MATCHESSolution

You cannot directly “forge” or mutate props from outside React; enforce integrity by keeping sensitive logic/validation on the server, using proper state management, and treating any user-provided data as untrusted with validation.

MATCHESSolution

Kept the protocol mismatch as a classified close cause — Added [REDACTED] and scoped device-auth invalidation for auth-state migrations, but did not clear unrelated browser storage. Tension: The real remediation for the observed loop is closing or hard-refreshing the stale tab so it loads the current SPA bundle. Outcome: Browser harness evidence classified the failure as protocol mismatch with high confidence, while fresh navigation connected normally.
