Errors while exporting

I have no idea why those errors come out. I was working on armature animation, and everything was fine, I did so changes in Logic Tree but in my opinion it is fine, and somehow it crashes now while exporting.

I need to export this to HTML file.

Why is that ?

Please help!

Hello! And welcome to our forum!
This is a bug. It is already fixed and you can check it in the upcoming developer preview. Temporary solution is to delete socket in 'Switch Select' node and add it again.
