Pipeline attachment - multiple doc

Elastic Search
1

Hi there, im trying to post multiple attachments for index. Same example we have on official. This is my mapping:

PUT _ingest/pipeline/attachment
{
  "description" : "Extract attachment information from arrays",
  "processors" : [
    {
      "foreach": {
        "field": "attachments",
        "processor": {
          "attachment": {
            "target_field": "_ingest._value.attachment",
            "field": "_ingest._value.data"
          }
        }
      }
    }
  ]
}

This is a main body:

{
  "attachments" : [
    {
      "filename" : "ipsum.txt",
      "data" : "dGhpcyBpcwpqdXN0IHNvbWUgdGV4dAo="
    },
    {
      "filename" : "test.txt",
      "data" : "VGhpcyBpcyBhIHRlc3QK"
    }
  ]
}

Im getting response:

{
    "error": {
        "root_cause": [
            {
                "type": "mapper_parsing_exception",
                "reason": "failed to parse field [attachments] of type [text] in document with id '203'. Preview of field's value: '{filename=ipsum.txt, data=dGhpcyBpcwpqdXN0IHNvbWUgdGV4dAo=, attachment={content_type=text/plain; charset=ISO-8859-1, language=en, content=this is\njust some text, content_length=24}}'"
            }
        ],
        "type": "mapper_parsing_exception",
        "reason": "failed to parse field [attachments] of type [text] in document with id '203'. Preview of field's value: '{filename=ipsum.txt, data=dGhpcyBpcwpqdXN0IHNvbWUgdGV4dAo=, attachment={content_type=text/plain; charset=ISO-8859-1, language=en, content=this is\njust some text, content_length=24}}'",
        "caused_by": {
            "type": "illegal_state_exception",
            "reason": "Can't get text on a START_OBJECT at 1:17"
        }
    },
    "status": 400
}

I would apprechiate any suggestion on, what's wrong here, i guess mapping should be changed, but not sure (new to elastic).
Thanks

Welcome!

I guess you are calling the PUT/POST _doc API, right?

What is the mapping of your index?

Yes, im calling put/post _doc api.

This is mapping of my index:

I got it work after i've deleted and created index again. Probably because of old updated mapping was incorrect.
