Query with lookups in FilteredAggregator fails with this exception in router, ``` Cannot construct instance of `org.apache.druid.query.aggregation.FilteredAggregatorFactory`, problem: Lookup [campaigns_lookup[campaignId][is_sold][autodsp]] not found at [Source: (org.eclipse.jetty.server.HttpInputOverHTTP); line: 1, column: 913] (through reference chain: org.apache.druid.query.groupby.GroupByQuery["aggregations"]->java.util.ArrayList[1]) ``` The problem is that constructor of `FilteredAggregatorFactory` is actually validating if the lookup exists in this statement `dimFilter.toFilter()`. This is failing on the router, which is to be expected, because, the router isn’t assigned any lookups. The fix is to move to a lazy initialisation of the `filter` object in the constructor. -- This is an automated message from the Apache Git Service.
