#  JSON\_API\_CACHE\_VALIDATION\_ERRORS 

```ts
const JSON_API_CACHE_VALIDATION_ERRORS: boolean | null;
```

Defined in: [warp-drive-packages/build-config/src/canary-features.ts:142](https://github.com/warp-drive-data/warp-drive/blob/4418225138f47a5fe1f4d7ca2b61c01e985a415d/warp-drive-packages/build-config/src/canary-features.ts#L142)

This upcoming feature adds a validation step to payloads received
by the JSONAPICache implementation.

When a request completes and the result is given to the cache via
`cache.put`, the cache will validate the payload against registered
schemas as well as the JSON:API spec.
