Hi. I'm trying to define a mapping for a transform. But any attempt to read the field I want to examine results in "Bad Request: [script_exception] runtime error".
{
"target_id": {
"type": "keyword",
"script": {
"source": "if (doc.containsKey('user_id') && doc['user_id'] != null) {emit('foo')}"
}
}
}
The first part of the boolean expression run but the second part:
doc['user_id'] != null
Causes the error. Have also tried doc['user_id'].value != null. Basically I seem to be unable to read this field at all except check if the map contains it. I have nothing else to go other than "runtime error". Its mapped as a keyword.
The stdout log was
