PINIA_COLADA_R0008: missing getPreviousPageParam

• Level: error (thrown, dev only)

What happened

loadPreviousPage() was called on an infinite query that does not define getPreviousPageParam in its options. Without it, Pinia Colada cannot compute the parameter of the previous page. This will fail in production where the development check is removed.

How to fix it

Add a getPreviousPageParam() function to the useInfiniteQuery() options:

useInfiniteQuery({
  key: ['messages'],
  query: ({ pageParam }) => fetchMessages({ cursor: pageParam }),
  initialPageParam: null as string | null,
  getNextPageParam: (lastPage) => lastPage.nextCursor,
  getPreviousPageParam: (firstPage) => firstPage.previousCursor, 
})

Common causes

• Calling loadPreviousPage() on a query that only paginates forward
• Forgetting getPreviousPageParam when adding bidirectional pagination
