Exception that occurs when accessing data without data
Describe the bug I am making a program for MacOS/Windows. I want to receive focus and send data continuously whenever the Enter key is pressed as a keyboard event in SearchField. In order to prevent the suggestions list from being displayed every time the focus comes, I did the following, but an exception occurred at a specific location in SearchField.
