I am trying to use nil
in a script field, but I get an error
GroovyScriptExecutionException[MissingPropertyException[No such property: nil for class: b5366a2d2ac98dae978423083f8b09e5cddc705d]]
Here is a demonstration script.
{
"query": {
"match_all": {}
},
"script_fields": {
"test": {
"script": "nil"
}
},
"size": 10
}
Really, any script with nil
will return this error (also scripts with begin
and end
also fail)
What type of Ruby is Elasticsearch using as a scripting language? Must I import nil
first? How do I do use nil
in a script?
Thanks
PS: For the pedantic, my real script is trying to get the length of a string:
doc["name"].empty ? nil : doc["name"].value.length()
