URBANopt - additional_mapper_measures

Hi.
Tried to run the DF sample “from_building_solids”.
Get the following at the DF_RunURBANopt component (v 1.1.4):

Runtime error (TypeErrorException): base_honeybee_osw() got an unexpected keyword argument ‘additional_mapper_measures’

Traceback:
line 128, in script

I installed URBANopt 0.5.0 and OS 3.1 following the compatibility matrix.

Any ideas?
Thanks,
-A.

p.s. Downgraded to UO 0.3.1 but still get the same error.
