ScaleFast 1.0.3 won’t launch

Trying to launch ScaleFast 1.0.3, two compatible .ufo's open. It throws this error in the output window:

Traceback (most recent call last):
  File "/Applications/RoboFont.app/Contents/Resources/lib/python3.7/fontParts/base/component.py", line 277, in _drawPoints

During handling of the above exception, another exception occurred:

Any help appreciated!

The error is self-explanatory. You are trying to subscript an object which you think is a list or dict, but actually is None. This means that you tried to do:

None[something]

This error means that you attempted to index an object that doesn't have that functionality. You might have noticed that the method sort() that only modify the list have no return value printed – they return the default None. 'NoneType' object is not subscriptable is the one thrown by python when you use the square bracket notation object[key] where an object doesn't define the getitem method . This is a design principle for all mutable data structures in Python.

This is working now, thanks!

Updated to the latest version, 1.0.5.

@frederik please mark as solved.

Kris

Yeah, restarted after install. Email sent ✌️

frederik

Yes, please do (or dummy ufo with the same problem)

You did restart RF after installing the latest version of ScaleFast?

Kris

Ah, thanks mate! I’ve updated the extension, but still giving the same error. However, it works on different .ufo’s. Can I email you the .ufo's that don’t work?

frederik

should be fixed and ready in Mechanic

good luck!!
