Solve the following python programming problem given the following code:
@ silencestderr 
def test_absolute_requests(self) : 
    def asserting_app(environ, start_response) : 
        assert (environ ['HTTP_HOST'] == 'surelynotexisting.example.com:1337') 
        assert (environ ['PATH_INFO'] == '/index.htm') 
        assert (environ ['SERVER_PORT'] == addr.split (':') [1]) 
        start_response ('200 OK', [('Content-Type', 'text/html')]) 
        return [b'YES'] 
(server, addr) = run_dev_server (server) 
    conn = httplib.HTTPConnection (addr) 
    conn.request ('GET', 'http://surelynotexisting.example.com:1337/index.htm') 
    res = conn.getresponse () 
    assert (res.read () == b'YES') 

    
    

    Fix the buggy line: (server, addr) = run_dev_server (server)
