Fragment is never used

Response from graphql server is: Fragment "___profile___requestIndex_1___userPhotoThumb" is never used. But the problem is in the apollo-client 😦

I have next query via graphql decorator:

  query profile($slug: String!) {
    viewer {
      id,
    }
    user(slug: $slug) {
      id,
      ...userPhotoThumb,
    }
  }

On the server side rendering everything works fine. But when I try to continue on the client side I will get next response from graphql:

{
  "errors": [
    {
      "message": "Fragment \"___profile___requestIndex_1___userPhotoThumb\" is never used.",
      "locations": [
        {
          "line": 16,
          "column": 1
        }
      ]
    }
  ]
}

The problem is that request from apollo-client is

"query ___composed {
  ___profile___requestIndex_1___fieldIndex_0: viewer {
    id
    __typename
  }
  ___getViewer___requestIndex_2___fieldIndex_0: viewer {
    id
    __typename
  }
}

fragment ___profile___requestIndex_1___userPhotoThumb on User {
  ___profile___requestIndex_1___fieldIndex_1: picture
  ___profile___requestIndex_1___fieldIndex_2: slug
  ___profile___requestIndex_1___fieldIndex_3: __typename
}
"

As you can see “user” part is completely missing in the profile query. I think that user part is cached from server side rendering

Here is a complete graphql request

{
    "debugName": "___composed",
    "query": "query ___composed {\n  ___getViewer___requestIndex_0___fieldIndex_0: viewer {\n    id\n    __typename\n  }\n  ___profile___requestIndex_1___fieldIndex_0: viewer {\n    id\n    __typename\n  }\n  ___getViewer___requestIndex_2___fieldIndex_0: viewer {\n    id\n    __typename\n  }\n}\n\nfragment ___profile___requestIndex_1___userPhotoThumb on User {\n  ___profile___requestIndex_1___fieldIndex_1: picture\n  ___profile___requestIndex_1___fieldIndex_2: slug\n  ___profile___requestIndex_1___fieldIndex_3: __typename\n}\n",
    "variables": {
        "___profile___requestIndex_1___slug": "zlatko-fedor"
    }
}

I have tried apollo-client 0.4.19 and 0.4.20 with same results. In this moment I am not able to use fragments anymore. Please help me to fix this issue. Thank you very much

I can confirm it is fixed in the 0.5.0-1

@seeden ah, ok, makes sense. It’s exactly what you suspected. We removed the query diffing functionality, so the next version won’t contain that bug any more 😃
