Top_children and has_child together in query

Hi,

I have three level schema for index which is like:

conversation
|----message
|-------message_tag

Now if run following query on message, it returns results
correctly.

{
"query": {
"has_child": {
"type": "message",
"query": {
"match_all": {}
}
}
}
}

Now if I put query above in query part of top_children on
conversation, it does not return anything and returns some errors with
200. I am trying to get top conversations with messages having
children.
{
"query": {
"top_children": {
"type": "message",
"score": "sum",
"query": {
"has_child": {
"type": "message_tag",
"query": {
"match_all": {}
}
}
}
}
}
}

Results:
{"took":3,"timed_out":false,"_shards":{"total":5,"successful":
3,"failed":2,"failures":[{"index":"testcompany","shard":
0,"reason":"QueryPhaseExecutionException[[testcompany][0]:
query[score_child[message/conversation]
(filtered(ConstantScore(child_filter[message_tag/message]
(filtered(ConstantScore(:))-

FilterCacheFilterWrapper(_type:message_tag))))-
FilterCacheFilterWrapper(_type:message))],from[0],size[10]: Query

{"index":"testcompany","shard":

(filtered(ConstantScore(:))-
FilterCacheFilterWrapper(_type:message_tag))))-
FilterCacheFilterWrapper(_type:message))]]]; nested: "}]},"hits":
{"total":0,"max_score":null,"hits":}}

I am new to Elasticsearch, so is this supposed to work or I am doing
something wrong.

Thanks,
Deepak

Sorry for typo:
the first query is

{
"query": {
"has_child": {
"type": "message_tag",
"query": {
"match_all": {}
}
}
}

Did not fully understand what you execute, can you gist a full sample? See Elasticsearch Platform — Find real-time answers at scale | Elastic.
