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.
