How to get the current entry of a foreach pipeline instruction using painless scripting?
I am trying to count JSON objects based on a flag.
To do so, I created two foreach pipelines iterating over my objects.
I want to count all the objects in the documents
array for which the field "count"
is set to true
.
POST _ingest/pipeline/_simulate
"pipeline":
"description":"...",
"processors":[
"set":
"field":"specific.docCount",
"value":0
,
"foreach":
"field":"data.status.transactions",
"processor":
"foreach":
"field":"_ingest._value.documents",
"processor":
"script":
"lang":"painless",
"inline":"if (ctx.count) ctx.specific.docCount += 1"
]
,
"docs":[
"_source":
"data":
"status":
"transactions":[
"id":"123",
"documents":[
"count": true
,
"count": false
]
]
]
I'm getting the following error :
"docs": [
"error":
"root_cause": [
"type": "exception",
"reason": "java.lang.IllegalArgumentException: ScriptException[runtime error]; nested: NullPointerException;",
"header":
"processor_type": "foreach"
],
"type": "exception",
"reason": "java.lang.IllegalArgumentException: ScriptException[runtime error]; nested: NullPointerException;",
"caused_by":
"type": "illegal_argument_exception",
"reason": "ScriptException[runtime error]; nested: NullPointerException;",
"caused_by":
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"if (ctx.count) ",
" ^---- HERE"
],
"script": "if (ctx.count) ctx.stats.docCount += 1",
"lang": "painless",
"caused_by":
"type": "null_pointer_exception",
"reason": null
,
"header":
"processor_type": "foreach"
]
This foreach pipeline doc suggests to use ctx
to refer to the ingest document, but I am not sure how to use this in my case.
How can I retrieve the current "foreach entry" in my painless script ?
