Manage JSON objects (scalars) with dgsQueryExecutor

[dmesa1988]

Hello,

We successfully made queries and mutations using the JSON scalar with DGS ('com.netflix.graphql.dgs:graphql-dgs-extended-scalars'). However, we are now trying to test it using the DgsQueryExecutor.executeAndExtractJsonPathAsObject, but we are unable to find a way to get the parsed object.

 it("Should return specific show when pass a title filter") {
                val advertiserList= dgsQueryExecutor.executeAndExtractJsonPathAsObject("""
                {   
                      advertisers{
                        totalElements
                        totalPages
                        content{
                          name
                          id
                          adSets{
                           renderId                                                     
                          }                                                     
                        }
                      }
                    }
                    """.trimIndent(), "data.advertisers.content",
                    object : TypeRef<List<Advertiser>>() {})
