Solve the following python programming problem given the following code:
def fake_get_object(self, container, name, resp_chunk_size = None) : 
    name = name [len ('non-existent/') :] 
    if (not os.path.isfile ((base.samples_path ('samples') + name))) : 
        return ({ 
            
}, None) 
if _object_body : 
        def _object_body() : 
            with open ((base.samples_path ('samples') + name)) as f : 
                buf = f.read (resp_chunk_size) 
                while buf : 
                    (yield buf) 
                    buf = f.read (resp_chunk_size) 
object_body = _object_body () 
else : 
        with open ((base.samples_path ('samples') + name)) as f : 
            object_body = f.read () 
resp_headers = os_loganalyze.util.get_headers_for_file ((base.samples_path ('samples') + name)) 
    return (resp_headers, object_body) 

    
    

    Fix the buggy line: if _object_body :
