React-apollo: useQuery does not run on the client when ssr=false

[baldurh]

Intended outcome:

useQuery(query, { ssr: false }) runs on the client side on page load in an SSR application.

Actual outcome:

It is not being run. It seems it is hydrating with null and is therefore not firing the query on the client on load. This works using the <Query> component and there are no results for this query in the hydration data from the server.

How to reproduce the issue:

Haven’t created a repro yet. I can do that if you’re not able to surface the bug.

This should be fixed in React Apollo 3.1.0, but let us know if not. Thanks!

@hwillson I was able to reproduce the error using both <Query ssr={false}> component and useQuery(QUERY, {ssr: false}).
