Hi,

I am trying to use ingest node to parse lines from filebeat.  
I used grok debugger to get to the pattern.  
My json file is like this:

{  
"description": "Test pipeline",  
"processors": [  
{  
"grok": {  
"field": "message",  
"patterns": ["%{YEAR:year}-%{MONTHNUM:month}-%{MONTHDAY:day} %{HOUR:hour}:%{MINUTE:minute}:%{SECOND:second};(?[^;]_);(?[^;]_);(?[^;]_);(?[^;]_);(?[^;]_);(?\<x\_7\>[^;]_);(?\<x\_8\>[^;]_);(?\<x\_9\>[^;]_);(?\<x\_10\>[^;]_);(?\<response\_time\>[^;]_)"]  
}  
}  
]  
}

When I run :  
curl -H 'Content-Type: application/json' -XPUT '[http://localhost:9200/\_ingest/pipeline/test-pipeline](http://localhost:9200/_ingest/pipeline/test-pipeline)' -d@ingest.json

I get  
{"error":{"root\_cause":[{"type":"parse\_exception","reason":"Failed to parse content to map"}],"type":"parse\_exception","reason":"Failed to parse content to map","caused\_by":{"type":"json\_parse\_exception","reason":"Unrecognized character escape ';' (code 59)\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@3168841; line: 1, column: 247]"}},"status":400}

Why is this??! Thanks! João

I don't see an issue eyeballing it

go to [https://grokdebug.herokuapp.com/](https://grokdebug.herokuapp.com/) and work out your syntax , there is obviously something in there that is wrong

also, don't know why you are escaping the ; it is not a regex character so it does not have to be escaped
