Hi All,
Could someone help me with sample json parsing using elasticsearch pipeline.
I am creating following pipeline in Elasticsearch 5.4.
PUT _ingest/pipeline/abc
{
"description" : "ABC",
"processors" : [
{
"json" : {
"field": "_source",
"target_field": "json_target"
}
}
]
}
When i do simulate test on this pipeline. I am getting error "java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: field [_source] not present as part of path [_source]"
POST _ingest/pipeline/abc/_simulate
{
"docs" : [
{
"_index": "index",
"_type": "type",
"_id": "id",
"_source": {"foo": 200 }
}
]
}
Error

"root_cause": [

"type": "exception",
