Fails to parse ES query result

Describe the bug Cubejs fails to parse ES query result.

To Reproduce Steps to reproduce the behavior:

1. Create a valid cube schema connecting to AWS ES 7.7
2. Build a query using cubejs play ground with just measure and dimension
3. Run the query
4. See error

Expected behavior Generated SQL query from cubejs log can be copied to kibana and executed successfully. So, query result should be shown in chart.

Screenshots Screen shot attached.
