   I noticed this same issue recently. @Synforge were you able to contribute to a solution for this? 
   
   At the moment we've just used the following work around (in native query), to ensure any "multi value" dimensions are flattened on response from rows in heap:
   ```
   array_to_string(non_mv_dimension, '')
   ```
