‘NoneType’ object has no attribute ‘X’No attribute "X"

I am trying to start my simulation with the component Run daylight Simulation and I got that:

Runtime erro (MissingMemberException): ‘NoneType’ object has no attribute ‘X’

Traceback :

line 2685, in testPtsStr, »<string> »

line 1530, in writeTestPtFile, « <string> »

line 159, in main, « <string> »

line 212. In script

Hi Sebastien, The test point list is empty since you’re passing an empty list of test surfaces to the component. I just removed the item selector and it works fine. Attached!
