Error when limit is not set for some queries

[ajkannan]

When users run queries that have many results or run multiple queries concurrently, they can see an "internal error" (500). When users set a limit on the query results, they may stop getting the error. A work around for users is to set a limit for the number of results to return. Then the user can use the end cursor from the first query's response as the start cursor for the next query request to get the next set of results.

Closing this as this should be fixed in v1beta3.
