Database queries through getEntityRecords initially return null while the asynchronous request completes, then provide cached data on subsequent calls. Always handle null states with loading indicators or conditional rendering.
REST API data structure differs from PHP WP_Post objects, providing raw and rendered versions of content fields. Console.log returned data to understand the structure before implementing display logic.
When rendering lists in React, each item must have a unique key prop to enable proper reconciliation. Use database IDs or other unique identifiers to satisfy React’s list rendering requirements.
