PixelStream hard crash editor

I’m having an issue with sending a command from UE4 to the player webpage, I believe I have followed the tutorial correctly, however for me the editor crashes on play. Using 4.24.2

Steps to reproduce:

Start a new project
Enable PixelStream plugin
Restart editor
Create a dummy blueprint actor
Add "PixelStreamerInput component to blueprint actor
Place blueprint actor into scene
Set blueprint actor in scene to receive auto input from Player0
Left mouse click and editor crashes.
Attached is the blueprint node setup.

Any ideas as to what I could be doing wrong? Thanks
