c# - Elasticsearch 5.6：路径 [xxxxxx] 下的 [nested] 嵌套对象不是嵌套类型

Question

我正在尝试升级到 elasticsearch 5.6，并且在执行请求时收到以下错误。它在我们运行多年的早期版本中运行良好。有任何想法吗？

{"type":"illegal_state_exception","re​​ason":"[nested] 路径 [categories] 下的嵌套对象不是嵌套类型"}

这是我的映射：

    .Mappings(mappings => mappings
        .Map<ESProduct>(product => product
            .AutoMap()
            .Properties(prop1 => prop1
                .Nested<ESCategory>(n => n
                    .Name("categories")
                    .AutoMap()
                    .Properties(props => props
                        .Keyword(s => s.Name(p => p.Id).Index())
                        .Keyword(s => s.Name(p => p.Name).Index())
                        .Text(s => s.Name(p => p.Path)
                            .Analyzer("path_analyzer")
                            .Index()
                        )
                        .Text(s => s.Name(p => p.IdNamePath)
                            .Fielddata(true)
                            .Analyzer("path_analyzer")
                            .Index()
                        )
                    )
                )

我的要求是这样的：

{
    "aggs":{
        "agg_manufacturers":{
            "terms":{
                "field":"manufacturer.idName",

            }
        },
       "cat_nest":{
           "aggs":{
               "agg_categories":{
                   "terms":{
                       "field":"categories.idNamePath",

                       "size":10000
                   }
               }
           },
           "nested":{
               "path":"categories"
           }
       }
   },
   "query":{
       "bool":{
           "must":[
               {
                   "nested":{

                       "query":{
                           "term":{
                               "categories.path":{
                                   "value":"10000/13168"
                               }
                           }
                       }
                   }
               },
               {
                   "bool":{
                       "should":[
                           {
                               "term":{}
                           }
                       ]
                   }
               },
               {
                   "term":{}
               }
           ]
       }
   },
   "size":0
}
