I have a MongoDB query: var queryLookup = {from:'fromCollection',localField:'field',foreignField:'otherField',as:'lookup_info'} [login to view URL]({$match:queryObj},{$lookup:queryLookup},{$project:queryProject},{$sort:sortObj}).toArray(function(err,items){}); However, the lookup_info value is an array with the first element being the entire set of data fields from the 'fromCollection'. So 'lookup_info' looks like this: lookup_info: [{'field1':'val','field2':'val','field3':'val','field4':'val'}] and instead I want this (notice, no array): lookup_info: {'field1':'val','field4':'val'}
