Linting tool Invalid Aura API error

The below line of code is showing warning like in the image


As per the documentation below are not valid

Aura.something(); // Use $A instead
$A.util.fake(); // fake is not available in $A.util

But in the aura documentation isUndefinedOrNull method is available. Did anyone get this issue?

  • Can you please add your code as well in the question – maniac coder Sep 5 '19 at 0:21
  • i getting warning in the linting tool when ever i use this function $A.util.isUndefinedOrNull(someVar) – mohan Sep 25 '19 at 8:59

You can try using this in your javascript helper file

NotBlank : function(checkString) {
    return (checkString != '' && checkString != null &&
            !$A.util.isEmpty(checkString) && !$A.util.isUndefined(checkString));

This will work the same way "$A.util.isUndefinedOrNull" is supposed to work. For example,
