Mismatched Dispatch Contracts

dispatch-and-trigger-mismatch

Redux and React integration fails when dispatched action types or middleware triggers don’t match the contracts expected by slice reducers, listeners, and RTK endpoints, so state updates, mutation merges, and auth flows silently diverge or retry incorrectly.

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

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

Wrap you components that rely on React Query data — React Query data. Outcome: with Suspense and HydrationBoundary.

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

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

Cast through `unknown` first: `} as unknown as RequestInit)`. — Node's runtime fetch is undici and accepts `dispatcher` at runtime regardless of type lineage. Tension: This bypasses the structural overlap check entirely. Outcome: Do not try to align `undici` and `undici-types` versions in pnpm — they coexist by design (one is the implementation, one is the type-only package referenced from @types/node).

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

Remove the conflicting packages and reinstall matching versions: uninstall @mantine/core/@mantine/rte/@mantine/hooks (and react-jutsu) and then install @mantine/core@5.10.5, @mantine/rte@5.10.5, and @mantine/hooks@5.10.5. Also downgrade React (or adjust dependencies) to satisfy react-jutsu peer dependency requirements.

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

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

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

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

Use store.dispatch to dispatch actions before rendering the component

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

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

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

Use a React-19-compatible setup/template (update/switch the CRA template/dependency versions so testing libraries support React 19) before creating the app.

MATCHESSolution

case "CallbackRouteError": return { error: "Invalid credentials!" } — in my `login.ts` server action in the switch case clause. Tension: to return the correct errors. Outcome: bypass this error.

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.
