The PolyScope caught a urcap exception.
I pressed the OK button by mistake.
How to get a popped up stack trace again.(The exception is low recall)
Is it in any logs?
The stack trace will be visible in the terminal in which the robot runs. If you have turned the robot off since the exception was caught, then it will no longer be visible.
Assuming you are on a real robot, you can plug in a USB keyboard in order to view the robots terminal.Details about doing so can be found in this thread
