Hello Elastic folks,
I need to run a script that gets data from index_a to index_b with some basic ETL.
This works well except I can't figure out the syntax for accessing a nested field like:
"transitions": {
"properties": {
"channel": {
"type": "keyword"
},
"created_at": {
"format": "epoch_millis",
"type": "date"
},
My _reindex
script looks like this:
if (ctx._source.transitions != null && ctx._source.transitions.created_at != null) {
ctx._source.transitions.created_at =
ctx._source.transitions.created_at / 1000000;
}
…and returns the error
"script_stack" : [
"if(ctx._source.transitions!=null&&ctx._source.transitions.created_at!=null){",
" ^---- HERE"
],
…
"caused_by" : {
"type" : "illegal_argument_exception",
"reason" : "Illegal list shortcut value [created_at]."
It feels like I'm missing something obvious.
Thanks for your help!
