Laravel Throwable not handle exception - get 500 internal error

Question

In Laravel I have the following controller and method:

public function uploadattachment(Request $request)    
{
    
    try {
        $aa = 3/0;
    }
    catch (Throwable $t) {
      
        return response()->json([
            'status' => 'Error', 
            'message' => $t->getMessage()
        ]);
    }
}

When I call above method from Angular I get error 500 internal server error. I thought that I will receive 200 and exception will be handled in catch clause in message property

Throwable is under Exception. If dividing by zero is handled by Exception it should be by Throwable as well: division by zero
