I am trying to use Ingest pipeline for nested object and I am getting error.

```
        "type" : "ingest_processor_exception",
        "reason" : "java.lang.IllegalArgumentException: field [content] not present as part of path [content]",

```

This is my Index which has nested type..

    "incidentId": {

    }
    }
    }

```

my ingest pipeline is

`{"description":"Document attachment pipeline","processors":[{"attachment":{"field":"content","target_field":"attachment"}},{"remove":{"field":["content"]}}]}`

Actual C# Code using NEST:  
var IngestPipeline = \_esProvider.Client.Ingest.PutPipeline("attachments", p =\> p  
.Description("Document attachment pipeline")

```
                        .Processors(pr => pr
                       
                        .Attachment<Document>(a => a
                           
                            .Field(f => f.Content)
                            
                            .TargetField(f => f.Attachment)
                           
                          )
                               .Remove<Document>(r => r
                  .Field(f => f.Field(cx => cx.Content))
              )
                        )
                        );

        } 

```

Index is getting created but when i try to create document it gives below error

"type" : "ingest\_processor\_exception",  
"reason" : "java.lang.IllegalArgumentException: field [content] not present as part of path [content]",

I think my ingest pipeline is not properly mapped with Document type which is nested type of Incident.

I am new to elastic search. Can you please guide me for this issue?
