How to throw error if data is invalid

[dominictobias-bullish]

const queryClient = new QueryClient({
  defaultOptions: {
    queries: {
      onSuccess: (data: any) => {
        // Eden Treaty doesn't throw errors I raised an issue:
        // https://github.com/elysiajs/elysia/issues/651
        // throw it ourselves so we can properly depend on `error` being filled
        if (typeof data === 'object' && data.error) {
          throw new Error(data.error)
        }
      },
      useErrorBoundary: true,
    },
  },
})

This doesn't work as expected because the error is actually thrown into the app. I don't want to wrap every component that uses useQuery in a boundary (and that is too broad anyway).

What I expected was that the error object becomes filled with the error instead of userQuery thinking the request was successful.

you would do that from within the queryFn. onSuccess is deprecated in v4 and was removed in v5
