DBD fails with "column storage_containers.storage_type does not exist"

Hi, 
I'm using a 24-node enterprise mode Vertica DB version 12.0.4-25.

I wanted to redesign an old projection and get recommendations on encoding and compression for my table columns. 

Using this function (that used to work in previous versions): 

select DESIGNER_DESIGN_PROJECTION_ENCODINGS('my_projection'); 

Produced this error:

DDT statement interfered with Database Designer
Column "storage_containers.storage_type" does not exist

Indeed I saw that that column was deprecated in previous versions, unfortunately Vertica QA missed this when removing the column. 

Trying a more complete design process eventually failed for the same reason

Does anyone know about this? 
Is there a workaround? 

Thanks!
