I've created a simple firebase data set to test some REST calls with (see the image below). I'm wondering why, when I query the collections in the database, firebase always return a null row first and then the actual rows. Here is what I get when I export the data. Notice the null rows under systems and system_types:\[code\]{ "systems" : [ null, { "system_type_id" : 2, "name" : "Commodore 128", "id" : 1 }, { "system_type_id" : 1, "name" : "Difference Engine", "id" : 2 }, { "system_type_id" : 2, "name" : "Osborne", "id" : 3 } ], "system_types" : [ null, { "name" : "Babbage", "id" : 1 }, { "name" : "Von Neumann", "id" : 2 } ]}\[/code\]
