Solve the following python programming problem given the following code:
def test_on_error_resume_next_single_source_throws(self) : 
    ex = 'ex' 
    scheduler = TestScheduler () 
    msgs1 = [on_error (230, ex)] 
    o1 = scheduler.create_hot_observable (msgs1) 
    def create() : 
        return Observable.on_error_resume_next (o1) 
results = scheduler.start (scheduler) 
    results.messages.assert_equal (on_completed (230)) 

    
    

    Fix the buggy line: results = scheduler.start (scheduler)

#Here is Python code to fix the buggy line: results = scheduler.

results = scheduler.start (def create()
