Solution

The first step in troubleshooting this issue is to identify the exact error message that is being displayed.

Additionally, you can check the application’s log files to see if there are any clues as to what might be causing the issue. If the error message is not clear, you may need to contact the application’s support team for assistance.


I think in your code you are comparing two strings using equals function like String1.equals(String2) in your case String1 is null (not initialized), and it is the root cause of this exception.

For example:

String string1 = getInputText();
boolean status = false;
if(string1 != null) {
    status = string1.equals(string2);
}

So please check and ensure String1 is not null before calling String1.equals(String2).
