Hi,
I'm working on an aggregation over an application metrics log. I have got the composite aggregate to work except when I had the section "status\_code", which is a nested aggregation, I get a 500 error with the status text of, "Cannot replay yet, collection is not finished: postCollect() has not been called"
Here's my agg query
{
"size": 0,
"track\_total\_hits": false,
"aggs": {
"c-buckets": {
"composite": {
"sources": [
{"time": {"date\_histogram": {"field": "@timestamp", "interval": "1m", "order": "asc"}}},
{"env": {"terms": {"field": "env.keyword"}}},
{"host": {"terms": {"field": "host.keyword"}}},
{"proxy\_host": {"terms": {"field": "proxy\_host.keyword"}}},
{"endpoint": {"terms": {"field": "api.endpoint.keyword"}}},
{"accept": {"terms": {"field": "api.accept.keyword"}}},
{"client\_key": {"terms": {"field": "api.client\_key.keyword"}}},
{"code\_version": {"terms": {"field": "code\_version.keyword"}}}
]
},
"aggs": {
"load": {"cardinality": {"field": "api.request\_id.keyword"}},
"threads": {"cardinality": {"field": "thread\_name.keyword"}},
"user\_name": {"cardinality": {"field": "api.user\_name.keyword"}},
"exceptions": {"value\_count": {"field": "stack\_hash.keyword"}},
"elapsed\_ms": {"extended\_stats": {"field": "api.elapsed\_millis", "sigma": 1}},
"started": {"filters": {"filters": {"start": {"match": {"message": "\ ***START**"}}}}},
"ended": {"filters": {"filters": {"end": {"match": {"caller\_method\_name.keyword": "logEnd"}}}}},
"long\_running": {"filters": {"filters": {
"lr": {"match": {"caller\_file\_name.keyword": "LongRunningRequestLogger.java"}},
"zombie": {"match": {"message": "ZOMBIE"}}
}
},
"aggs": {
"requests": {"cardinality": {"field": "api.request\_id.keyword"}}
}
},
"status\_code": {"terms": {
"field": "api.status\_code",
"collect\_mode" : "breadth\_first"},
"aggs": {
"elapsed\_ms": {"extended\_stats": {"field": "api.elapsed\_millis", "sigma": 1}},
"user\_name": {"cardinality": {"field": "api.user\_name.keyword"}},
"threads": {"cardinality": {"field": "thread\_name.keyword"}}
}
}
}
}
}
}
Is this the same thing referenced here? [Metric aggregation fails in composite aggregation](https://discuss.elastic.co/t/metric-aggregation-fails-in-composite-aggregation/119933)
Thanks,

This is working now with Elasticsearch 6.3.0
