"error" : "null exception" in timeseries query on Druid

I am using timeseries query on my indexed data, the snippets belows:

"queryType": "timeseries",
"dataSource": "statistic-test-v1",
"granualarity": "hour",
"descending": "true",
"aggregations":[{"type": "longSum", "name": "output_imp", "fieldName": "impression"}],
"intervals": ["2016-08-22T01/2016-08-22T02"]

I am ensure that it's exactively in intervals and aggreagations params. But when I use command line to query it:

curl -L -H'Content-Type: application/json' -XPOST --data-binary @quickstart/ants-data/time-series-query-statistic-test-v1.json http://localhost:8082/druid/v2/?pretty

The result like this:

"error" : "null exception"

Can anyone explain why it come to error and help me to fix it ? Thanks a billions.

It just simple mistake of synctax edit "granualarity" to "granularity", it works well.
