Cache Key / Tag Mismatch

cache-key-tag-mismatch

Cache entries are misidentified because key/tag schemes and client-context bindings don’t line up, so query invalidation and re-fetching either fail or trigger unexpectedly after mutations like completion or delete.

MATCHESSolution

You should really use tag validation to trigger your query endpoints to refetch upon any successful mutation. — onSuccess: async () => { await queryClient.invalidateQueries({ queryKey: ["vehicle.getVehiclesWithMakes"],. Tension: Both are less than ideal. Outcome: await queryClient.invalidateQueries({ queryKey: ["vehicle.getVehiclesWithMakes"], // <-- invalidates tag key });.

MATCHESSolution

handle a scenario when the code is fine but backend went offline — prefetching data with usePrefetchQuery. Tension: prefetch works.

MATCHESSolution

The blog post ID must be part of the key. — useQuery({. Tension: queryKey: ["getBlogPost"]. Outcome: queryKey: ["getBlogPost", blogPostId],.

MATCHESSolution

Setting `cacheTime: 0` solved it for me. — I was getting the same issue using `@tanstack/react-query@4.36.1`. Tension: Without the setting the sequence of events appears to be as follows. Outcome: In version 5, `cacheTime` has been renamed to `gcTime`.

MATCHESSolution

If true, staleness checks for cached data will be bypassed, but missing data will be requested from the server. Tension: Default: false. Outcome: To force full offline mode, use --offline.

MATCHESSolution

Use Next.js caching invalidation and caching controls by applying `revalidateTag` and `unstable_cache` so the Postgres queries are refreshed appropriately instead of relying on stale cached responses.

MATCHESSolution

provided it's called within the same process — workers might be pre-forked. Tension: the cache doesn't work across processes. Outcome: each process got its own cache.

MATCHESSolution

Try logging in with that key from your local machine. — The step syntax looks fine. Tension: The error is saying that the user on the host does not have a matching public key. Outcome: the wrong user.

MATCHESSolution

That's where the `restore-keys:` come in! — If there isn't an exact match for the `${{ runner.os }}-m2-v1-${{ hashFiles('**/pom.xml') }}`. Tension: it will look for the latest cache with the prefix `${{ runner.os }}-m2-v1-*`. Outcome: the runner would compare the contents at the end of the run and probably find out that files have changed.

MATCHESSolution

override the copy method, and use your own marshaller — inherit the AmazonS3Client class. Tension: your operations will succeed, although the tags behavior will not match the one you would expect with S3. Outcome: your operations will succeed, although the tags behavior will not match the one you would expect with S3.

MATCHESSolution

in the Developer-Tools the "Disable Cache" in the Network-Tab is NOT checked — locally developing. Tension: otherwise the caching won't work while developing. Outcome: caching won't work while developing.

MATCHESSolution

Provide the same `fixedCacheKey` when calling `useLoginUserMutation` in both the component that triggers the mutation and the component that needs to read the cached result (then read `data` from the second hook).

MATCHESSolution

Call each RTK Query hook with the exact same query arguments (or none, if the endpoint takes none) that the fulfilled requests use, and ensure components read the correct hook data/selector result corresponding to those cache entries.

MATCHESSolution

Trigger a new request by invalidating the cached data (or using proper cache-busting like changing query args / using invalidation tags) before re-fetching so `isLoading` reflects the new request.

MATCHESSolution

Add `providesTags` to `getTimeseriesFromTo` (returning `{ type: 'Timeseries', id: <derived id> }`) and/or invalidate that tag from the corresponding mutation endpoint using `invalidatesTags`.

MATCHESSolution

Update the getSingleUser cache from within getUsers (e.g., using onQueryStarted in getUsers to dispatch api.util.updateQueryData for getSingleUser by the user id). Alternatively, ensure consistent tag types/ids between endpoints and manually prefill/replace the target endpoint’s cache so it’s treated as already fetched.

MATCHESSolution

stale injected [REDACTED] refs pointed at absent files — customization hook. Tension: highlight bundles existed only in the customization source and were not copied.

MATCHESSolution

Remove the key vault collection drop and reuse an existing key by checking clientEnc.GetKeyByAltName before calling CreateDataKey

MATCHESSolution

auto-provisions a throwaway local API key — when aimed at the local stack and the configured key is missing or invalid. Tension: the configured key is missing or invalid. Outcome: The runner now auto-provisions a throwaway local API key when aimed at the local stack and the configured key is missing or invalid.

MATCHESSolution

Use cache-busting query strings on the remoteEntry URL and avoid caching the remote entry

MATCHESSolution

Use content hashes for chunk filenames to help invalidate changed assets

MATCHESSolution

Outcome: cache.clear().

MATCHESSolution

Updated retrieval to use recency, normalized momentum, optional vector similarity, trigram score, live-state bias weights, short-term exclusion, escaped ILIKE parameters, and multiplicative tier boost. — Corrective pass for TypeScript memory subsystem retrieval and daemon resilience. Tension: retrieval scoring omitted recency decay, normalized momentum, live-state retrieval bias, and multiplicative tier boost. Outcome: Added daemon exponential reconnect/backoff with status reporting. Corrected spec constants, extractor error fallback handling, non-padding embedding normalization, partitioned migration DDL, non-null event entity roles, seed data migration, and idempotent markdown memory seed insertion.

MATCHESSolution

Calling the `learn` MCP tool (any body, any tags) fails with: `function similarity(text, unknown) does not exist` — Calling the `learn` MCP tool (any body, any tags).

MATCHESSolution

after each allocation that may trigger GC. Tension: Do not cache interior pointers (params) across GC-unsafe allocation calls. Outcome: Apply same fix pattern to sampled_data_continue.

MATCHESSolution

Cache in OnAwake — Key s&box performance patterns from the optimizer skill:. Tension: GetComponent every frame. Outcome: Physics work in OnFixedUpdate.

MATCHESSolution

Content-hash dedup against existing entries — before inserting. Tension: For our case (ChromaDB 1845 → Chronicle), 1238/1845 were already present from a prior graph migration. Outcome: Only 607 net-new.

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.

MATCHESSolution

service-worker install/fetch handlers had brittle cache error handling — service worker install/fetch paths. Tension: brittle cache error handling. Outcome: tolerant precache and explicit offline responses.

MATCHESSolution

Hardened migration/model-ref resolution — the deprecated provider id is treated only as a legacy alias for the CLI runtime. Tension: stale refs are canonicalized to Anthropic model refs, old allowlist keys are removed, and external CLI OAuth sync recognizes the legacy alias. Outcome: external CLI OAuth sync recognizes the legacy alias.
