data and error fields in useQuery hook empty.

[daphnesmit]

This is probably an Apollo bug but wanted to double check.

I use apollo link rest like so:

query ContentPart($htmlUrl: String!) {
  contentPart(htmlUrl: $htmlUrl) @rest(type: "ContentPartHtml", path: ":htmlUrl") {
    id 
    html 
  }
}

const restLink = new RestLink({
    uri: BASE_URL_OF_API,
    customFetch: fetch,
    responseTransformer: async (response, typeName) => {
      const html = await response.text()
      return {
        id: response.url,
        html,
        __typename: typeName
      }
    }
});

return new ApolloClient({
    link: authLink.concat(restLink),
    cache,
})

Then I try to make use of Apollo clients useQuery:

  const {data, error} = useQuery(ContentPartDocument, {
    variables: {
      htmlUrl: url,
    },
    client,
   onCompleted:(data)=> console.log(data)
  })

Where the returned data and error from the useQuery hook are undefined, but the data in onCompleted is set and the call is made successfully...

Is this a bug in Apollo client?
