Null pointer exception using Global Aggregation and then Nested Aggregation #27928
Description
Elasticsearch version (bin/elasticsearch --version): 5.1.2
Plugins installed: []

openjdk version "1.8.0_151"

Description of the problem including expected versus actual behavior:
I just make a query with some filters and retrieve the corresponding documents. Also, I try to add aggregations about these documents with a NestedAggregation and without any filter used in the query so I used at the very beginning the GlobalAggregation.
When I make the request I get a Null Pointer exception from elastic log. However, I get results from aggregations but also, an error.
