Hello, I'm beginning writing scripts for Fusion 360, so far it seems like quite an awesome framework. I was hoping that someone could help me with the following two questions.
1. I am however trouble understanding if there's something I'm missing here to get the ValidateInputs event to fire at all.
2. I seem to get stuck with my VSCode responding to actions happening on Fusion 360 side (for example it just doesn't seem to activate breakpoints). I'm running Fusion 360 2.0.9642, and VSCode 1.52.1.
I've attached the code here, as far as I can understand I am plumbing up the ValidateInput event handler correctly, but I'm not sure. Thank you!
