Error in running code in YADE 2019.01a-2

Hello guys,

I recently I have installed YADE 2019.01a-2. So I put my previous codes to run them. The codes run correctly in YADE 2018.02b But I see the following error when running them in YADE 2019.01a-2:

TypeError: 'QCborSimpleType' object is not iterable
