The script that I created with the Legacy- components in the past has shown a warning and it has not worked. Ladybug tools 1.1.0 and 1.2.0 have been available currently. I was just wondering if I would need to change the components of the Legacy to the new components of the new versions.
It depends on the workflow you are trying to model. It is possible that the same workflow is not yet available in LBT 1.2. In that case, you’ll need to stick with the legacy plugin. In any case, you should share a simplified version of your file with necessary geometry internalized and also share what errors you are experiencing.
I tried you file and I am unable to re-create the error you shared. The file works without errors at my end. Can you try updating using Ladybug_Update Ladybug component?
