Can't find field <field> on object (ROOT_QUERY) undefined.

I’m using ReactNative, and am able to load a user object from my graphql server using

graphql(gql`{
    user(id: 1) {
        first_name
    }
}`)(DisplayComponent)

Therefore, I would expect this user to be in the cache. However, when I write the following code in the constructor of a different component:

apolloClient.readQuery({query: gql`
    query Test {
        user(id: 1) {
            first_name
        }
    }
`})

I get the following error: Can't find field user({"id":1}) on object (ROOT_QUERY) undefined.

For what it’s worth, I ran into the same issue and found out that I forgot the variables when calling readQuery:

const updateFunc = (cache, {data: {saveLibrary}}) => {
    const {libraries} = cache.readQuery({query: libQuery, variables: {id: saveLibrary.id}});
};

Maybe it can help someone 😃
