Gremlin Graph: Add support for array values in group() and groupCount()
You should be able to group by an array of values. it is perfectly valid to do a group() or groupCount() like so:
Other Graphs implementing Gremlin will give you a result, while CosmosDB fails with:
"Unexpected Error: Cannot resolve object to a primitive value."
We have reviewed this request and at this time this is not on our road map.
Will leave this open and review this in upcoming cycles for our road map.
