The method getMessage does only exist in ParseError, but not in Symfony\Component\Debug\...ion\FatalThrowableError.
                                                                                                                                                                                                        

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
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. 

  2. Only allow a single type to be passed if the variable comes from a parameter:
    

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