Database projection fails when omitting "_id" field

[axkrishnan]

I have the following test table:

I am trying to use the projection feature to exclude the "_id" field from the results like so:

precurl -X GET -H "X-Appery-Database-Id: 54011bace4b055c018db1489" -G --data-urlencode 'proj={"_id":0}' https://api.appery.io/rest/1/db/collections/projectme/pre

But I get the error: {"code":"DBSQ000","description":"This wasn't supposed to happen but an error occurred. Please try again. If the error persists please let us know on the http://appery.io/forum or email us: a href="mailto:support@appery.io" rel="nofollow"support@appery.io/a"}

Omitting the "name" field does not cause an error and works as expected:
precurl -X GET -H "X-Appery-Database-Id: 54011bace4b055c018db1489" -G --data-urlencode 'proj={"name":0}' https://api.appery.io/rest/1/db/collections/projectme

Response: [{"id":"54011bd9e4b055c018db148d","createdAt":"2014-08-30 00:33:29.704","_updatedAt":"2014-08-30 00:33:29.704"}]/pre

Hi axkrishnan,

Unfortunatly currently you can not exclude "_id" field.
