$e is of type object<Exception> , but the function expects a object<Throwable> .
It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { }
$x = '123'; // string "123"
// Instead of
acceptsInteger($x);
// we recommend to use
acceptsInteger((integer) $x);

The expression
$id of type null|string is loosely compared to true ; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.
In PHP, under loose comparison (like For '' == false // true
'' == null // true
'ab' == false // false
'ab' == null // false
// It is often better to use strict comparison
'' === false // false
'' === null // false
