Bug introduced by
The method getMessage does only exist in InvalidArgumentException, but not in Facade\Ignition\Exceptions\ViewException.

It seems like the method you are trying to call exists only in some of the possible types.

Let’s take a look at an example:

class A
{
    public function foo() { }
}

class B extends A
{
    public function bar() { }
}

/**
 * @param A|B $x
 */
function someFunction($x)
{
    $x->foo(); // This call is fine as the method exists in A and B.
    $x->bar(); // This method only exists in B and might cause an error.
}

Available Fixes

  1. Add an additional type-check:

    /**
     * @param A|B $x
     */
    function someFunction($x)
    {
        $x->foo();
    
        if ($x instanceof B) {
            $x->bar();
        }
    }
    
  2. Only allow a single type to be passed if the variable comes from a parameter:

    function someFunction(B $x) { /** ... */ }
