The variable
$lang does not seem to be defined for all execution paths leading up to this point.
If you define a variable conditionally, it can happen that it is not defined for all execution paths. Let’s take a look at an example: function myFunction($a) {
switch ($a) {
case 'foo':
$x = 1;
break;
case 'bar':
$x = 2;
break;
}
// $x is potentially undefined here.
echo $x;
}
In the above example, the variable $x is defined if you pass “foo” or “bar” as argument for $a. However, since the switch statement has no default case statement, if you pass any other value, the variable $x would be undefined. Available Fixes

This check looks for function or method calls that always return null and whose return value is assigned to a variable.
The method
getObject()
can return nothing but null, so it makes no sense to assign that value to a variable.The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes.
