Attachment Pipeline Support for Old MS Word and Excel Format

Hi All! I'm uploading a Microsoft Word in .doc format, instead of .docx, to Elasticsearch using attachment pipeline, and I receive the following response.

    "error": {
        "root_cause": [
                "type": "parse_exception",
                "reason": "Error parsing document in field [fileContent]"
        "type": "parse_exception",
        "reason": "Error parsing document in field [fileContent]",
        "caused_by": {
            "type": "no_such_file_exception",
            "reason": "/tmp/elasticsearch-8583309320442462221/apache-tika-15922682441714930542.tmp"
    "status": 400

Please advise if there's any limitation for the pipeline or any additional setup is required. Thanks in advance.


That's a weird error.
Is there a chance you could share your binary document?

Which Elasticsearch version are you using?

The version of my Elasticsearch is 7.12.0, and I installed ingest attachment plugin as introduced at Ingest Attachment Processor Plugin | Elasticsearch Plugins and Integrations [7.15] | Elastic
Please find my sample document and the request JSON here. Thanks.
