Missing value key in value count aggregation? (ES 1.3.0)

Elastic Stack Elasticsearch
1

Hi,

this looks like an error to me? I tried to order a terms aggregation by the
value count sub aggregation an Elasticsearch 1.3.0 throws the following
error: "ReduceSearchPhaseException[Failed to execute phase [query],
[reduce] ]; nested: ElasticsearchIllegalArgumentException[Invalid order
path [grades_count]. Missing value key in [grades_count] which refers to a
multi-value metric aggregation]; "

My Aggregation looks like this (this is only a dumbed down version to
demonstrate the error.)

"aggs": {
"students": {
"terms": {
"field": "name",
"order": {
"grades_count": "desc"
}
},
"aggs": {
"grades_count": {
"value_count": {
"field": "grades"
}
}
}
}
}

Regards,
Valentin

This does seem to be a bug. I have opened #7050
https://github.com/elasticsearch/elasticsearch/issues/7050 for this
