Steps to reproduce

• Download the 2.0.0a12 alpha build from here
• Create a new 2019.4.1f1 project and install the alpha by dragging and dropping the package
• Create a blank game object in the hierarchy
• Select the blank game object and add a new bolt class via the add component button in the inspector. 
• In the new bolt class creates a new flow graph. 
• Select the start function and add a debug.log and a sting Litteral node to it.
• Switch to Generated mode via the play options
• Press play

Notice issue >> NullReferenceException: Object reference not set to an instance of an object is constantly spewed to the log.
