Problem Description:
Passing an expression that uses the Safe Navigation Operator to the isNull function will always return true even if the value is not null. Storing the value in a variable first and passing that variable to isNull does not cause this issue.
Steps to Reproduce:
var a = {
b: {
c: 'test'
}
};
var Test = a?.b?.c;
var result1 = isNull( a?.b?.c );
var result2 = isNull( test);
Actual Result:
The variable Test will equal 'test'. The variable result1 equals 'YES'. The variable result2 equals 'NO'.
Expected Result:
It seems that result1 and result2 should both equal 'NO'.
Any Workarounds:
Store the value in a variable before passing it to isNull.
