Unsupported Input Variables

via #16

Thanks for fix this problem, but it still seems to have some little problem.

Here is my test code, use the last complex_example code with FastAPI -> https://gist.github.com/chiaki64/e5168279926f0cadeacba59f78c5eb2c

and the query string in playground

# Query
query Address($geo: GeoInput!) {
  address(geo: $geo) {
    latlng
  }
}

# Variables
{
  "geo": {
    "lat": 1.0,
    "lng": 2.0
  }
}

# Response
{
  "error": {
    "errors": [
      {
        "message": "'dict' object has no attribute 'body'",
        "locations": null,
        "path": null
      }
    ],
    "data": {}
  }
}

The debug logger shows

ERROR: 'dict' object has no attribute 'body'

AttributeError: 'dict' object has no attribute 'body'

the source variable type there should be <class 'graphql.language.source.Source'>, but now we get the type <class 'dict'>, so is this a problem of graphql package or pygraphy package?
