If you move the Motion Bro panel, there should be a magnifying glass icon in the orange warning bar. If you click that icon, it'll reveal the expression that contains the error. Can you expand that expression and share a screenshot? That'll help the community members to understand it better.
yeah i know its show the errors but i still cant figure out how to fix errors and there is a lot of them and some part of face tools layers missing i dont know how to fix that am i try a dowland new face tools effect for motion blur plug-in
