Redux Toolkit Action Mismatch

redux-action-endpoint-mismatch

Redux Toolkit state updates fail when dispatched action types or endpoint triggers don’t align with the slice/listener expectations (namespacing from createSlice, matcher/trigger composition, and RTK Query mutation merging).

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

this doesn't work for tanstack router. For example, I have a dynamic route `/items/$itemId.tsx`. Tension: it gives me an error that `$itemId.tsx` should be in kebab-case. Outcome: override Biome config to disable this rule in `routes`.

MATCHESSolution

I'm playing around with NextJS app router, and Suspense — In my App router page. Tension: this suspense boundary won't do anything.

MATCHESSolution

Align Tanstack Query package versions per the official React Query SSR/Next.js guide and use the correct SSR hydration components (Hydrate/DehydratedState/QueryClientProvider) as shown in the documentation.

MATCHESSolution

use hash-based routing — react + tanstack router + github pages. Tension: The default "browser" routing will exhibit the behaviour you describe.

MATCHESSolution

Lift mutation state to a shared owner (same parent) or to shared global/local state (React Context/Redux or local state in a shared parent), and update that state inside `onSuccess`/`onError`/`onSettled` (or `isPending`) callbacks; alternatively, read mutation status via the same `useMutation` instance passed/shared with the other component.

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

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

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

Do not reset the entire API slice state during the mutation lifecycle; instead rely on the sendLogout trigger promise/unwrap (or on isSuccess without resetting) to run navigate("/") after the mutation succeeds.

MATCHESSolution

convert the object into the builder callback syntax — createSlice({ name, initialState, reducers: { /* case reducers here */ },. Tension: object syntax for `createSlice.extraReducers` has been deprecated. Outcome: builder => { builder.addCase(todoAdded, (state, action) => {}) }.

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

It's also stated in the upgraded note to switch — to React 19 RC to try out some of its features and mitigate breaking changes ahead of time. Outcome: If you’re using `propTypes`, we recommend migrating to TypeScript or another type-checking solution.

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.
