I am running 7.17 ELS and trying to drop all docs which come from one specific host

```auto
		"drop": {
          "if" : ("agent.name" == 'ABC')
        },

```

I have added this as drop processor in ingest pipeline however it keeps on complaing about comple error and wont allow me to save it.

Any idea what may be wrong, i have gone thru internet for similar error however dont seem to find the root cause.

Hi @Atul_Chadha

Did you look at the docs [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/drop-processor.html) you have bad syntax Note the outer double quotes and the inner single quotes. Also you need to use the context `ctx` You should also read about null type safety and conditionals [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/drop-processor.html)

There's an excellent example, much like yours.

```auto
PUT _ingest/pipeline/my-pipeline
{
  "processors": [
    {
      "drop": {
        "description": "Drop documents with 'network.name' of 'Guest'",
        "if": "ctx?.network?.name == 'Guest'"
      }
    }
  ]
}

```

Thank you! It was indeed syntax error.
