Hello Everyone:

I am using Elasticsearch 7.8 version.

I have a mutliple conditions to be checked using set processor ...

I am using below code

```auto
curl -X POST "localhost:9200/_ingest/pipeline/_simulate?pretty" -H 'Content-Type: application/json' -d'
{
  "docs": [
    { "_source" : { "outer": {"inner": "X"} } },
    { "_source" : { "outer": {"inner": "Y"} } },
    { "_source" : { "outer": {"inner": "Z"} } },
    { "_source" : { "outer": {"inner": "T"} } }
    ],
  "pipeline": {
    "processors": [
      {
        "set": {
          "if": "ctx.containsKey('outer') && ctx['outer'].containsKey('inner') && ctx.outer.inner == 'Y'",
          "field": "added_field",
          "value": "added_value"
        }
      }
    ]
  }
}' -u $ES_USER:$ES_PASS

```

This code is not working and giving me ERROR :

```auto
{
  "docs" : [
    {
      "error" : {
        "root_cause" : [
          {
            "type" : "script_exception",
            "reason" : "compile error",
            "script_stack" : [
              "ctx.containsKey(outer) && ctx[outer].cont ...",
              " ^---- HERE"
            ],
            "script" : "ctx.containsKey(outer) && ctx[outer].containsKey(inner) && ctx.outer.inner == Y",
            "lang" : "painless",
            "position" : {
              "offset" : 16,
              "start" : 0,
              "end" : 41
            }
          }
        ],
        "type" : "script_exception",
        "reason" : "compile error",
        "script_stack" : [
          "ctx.containsKey(outer) && ctx[outer].cont ...",
          " ^---- HERE"
        ],
        "script" : "ctx.containsKey(outer) && ctx[outer].containsKey(inner) && ctx.outer.inner == Y",
        "lang" : "painless",
        "position" : {
          "offset" : 16,
          "start" : 0,
          "end" : 41
        },
        "caused_by" : {
          "type" : "illegal_argument_exception",
          "reason" : "Variable [outer] is not defined."
        }
      }
    },

```
