Misleading error message on has_parent query #35383
Description
Elasticsearch version 6.4.2
The has_parent query returns misleading error messages, referring to field type rather than field parent_type:
"type": "illegal_argument_exception",
"reason": "[has_parent] requires 'type' field"
and
"type": "parsing_exception",
"reason": "[has_parent] query does not support [type]",
To reproduce:
POST _search
{
"query": {
"has_parent": {
}
}
}
and
POST _search
{
"query": {
"has_parent": {
"type": "test"
}
}
}
