Problem with 'key_as_string' on Date Histogram Aggregation

[NativAt]

When I'm trying to parse response of Date Histogram Aggregation request. I'm not getting the "key_as_string" field, but just the bucket "key".

@NativAt, could you past your input data?

Please take a look here: https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-datehistogram-aggregation.html

Date Histogram "Format" response is in: "key_as_string" and not in "key" which gives you unix timestamp.

Please check my bugfix proposal.

median
