graphql usage

[dimentii]

Hi,
I could not find how to properly build GraphQLRequest object. Trying to build it like
body = GraphQLRequest( query="""query ReturnProductsIds($limit: Int!, $offset: Int!) { products( where: "masterData(published=true)" sort: "id asc" offset: $offset limit: $limit ) { results { id } } }""", variables=GraphQLVariablesMap([('limit', 500), ('offset', 0)]) )
and it doesn't work. After object serialization variables become empty dict which causes error response from commercetools API
Appreciate if you provide an example.
