How to launch WESTON with no input devices

Been working on a project to create s simple digital display using the Raspberry pi 4 and buildroot. It is a simple application that interacts with the user through bluetooth and displays some information on the attached HDMI screen. All the debuging and programming work has been done. APP works fine However after detaching the mouse and Keyboard; and setting up weston to launch automatically, it fails. If i attach a keyboard and reboot, it works fine and weston is launched. I did some digging and applied the configuration option require-input=false , but same problem. Is there something i am missing ? Regards
