URBANopt - DDY file error

Hi,
Trying to run the RunURBANopt i get the following error:
Runtime error (AssertionException): No design day objects found in .ddy file.

Traceback:
line 92, in from_ddy_file, “C:\Users\ayezi\ladybug_tools\python\Lib\site-packages\ladybug\ddy.py”
line 112, in add_from_ddy_996_004, “C:\Users\ayezi\ladybug_tools\python\Lib\site-packages\honeybee_energy\simulation\sizing.py”
line 113, in script

I believe it is somehow related to this discussion.
Thanks for any help you can give.

Yes. I have also encountered this problem.
Returning to your original post got me through the error for URBANOpt.

A similar problem is also occuring on the OSW side, if you do not rearrange the workflow to specifically provide a .ddy file.
