ignore_missing takes no effect when use template snippets in Rename Ingest Processor #74241
Description
Elasticsearch version: master
Plugins installed: []
JVM version (java -version): 14.0.1
OS version (uname -a if on a Unix-like system): Mac OS 10.13.6
Description of the problem including expected versus actual behavior:
When use template snippets in the field parameter of the rename ingest processor, and set ignore_missing to true, if the resolved field of the template snippets does not exist, the processor doesn't exit quietly but throw an exception.
Steps to reproduce:
POST _ingest/pipeline/_simulate
{
"pipeline" :
{
"description": "_description",
"processors": [
{
"rename" : {
"field" : "{{foo}}",
"target_field": "bar",
"ignore_missing": true
}
}
]
},
"docs": [
{
"_index": "index",
"_id": "id",
"_source": {
"message": "test"
}
}
]
}
The result is :
{
"docs": [
{
"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "path cannot be null nor empty"
}
],
"type": "illegal_argument_exception",
"reason": "path cannot be null nor empty"
}
}
]
}
