   > Is the intention to get the distinct values?
   
   Yes it is.
   
   > It didn't fail in 0.10.0 probably because the GROUP BY is ignored?
   
   Well we do get distinct values with 0.10, if i remove the group by on 0.11 i 
do get a result but not distinct.
   
   > To get the stack trace, can you try restarting the server and then issue 
the same query again?
   
   Thanks for the tip to restart it, here's the error:
   ```
   QueryExecutionError:\njava.lang.NullPointerException
   
org.apache.pinot.core.operator.transform.function.JsonExtractKeyTransformFunction.transformToStringValuesMV(JsonExtractKeyTransformFunction.java:90)

   ```
   
   NPE is 
[here](https://github.com/apache/pinot/blob/release-0.11.0/pinot-core/src/main/java/org/apache/pinot/core/operator/transform/function/JsonExtractKeyTransformFunction.java#L90)
 but i'm not sure to understand how this can throw a NPE ...
