filter and order seems not to work correctly

[JanEggers]

the code is here:

https://github.com/JanEggers/Playground/blob/queryBuilderExperiments/Playground.Core.Test/GraphQLClientTest.cs

when i try to execute a query i get an exception:

when i try to access the query property the query is not valid;

query ($where: CompanyFilterInput, $order: [CompanySortInput]) { result: companies (where: $where, order: $order) { 
  id
  name
  sites {
    id
    name
    companyId
  }
 } }

i would really love to use your library as it greatly reduces the complexities of creating valid queries.

Also it would be awesome if you could extract the filterinput and sortinput from the linq query instead of providing it separate to the query
