How solve this problem?
Solution exception: nonetype object has no attribute lower

Hi - you have posted this in the honeybee[+] category. According to the Food4Rhino page, that version is for Grasshopper 6 Win. From a previous post, it’s clear that you are running Rhino 5.
The Compatibility Matrix doesn’t mention all versions of the Ladybug tools, nor the required version of Rhino, but perhaps the version of Ladybug and Honeybee that you are running just doesn’t work on Rhino 5? @chris or @mostapha would know for sure…
