Solve the following python programming problem given the following code:
def __init__(self, pymux) : 
    self.pymux = pymux 
    def _handle_command(cli, buffer) : 
        ' When text is accepted in the command line. ' 
        text = buffer.text 
        pymux.leave_command_mode (cli, append_to_history = True) 
        pymux.handle_command (cli, text) 
def _handle_prompt_command(cli, buffer) : 
        ' When a command-prompt command is accepted. ' 
        text = buffer.text 
        client_state = pymux.get_client_state (cli) 
        prompt_command = client_state.prompt_command 
        pymux.leave_command_mode (cli, append_to_history = True) 
        pymux.handle_command (cli, prompt_command.replace ('%%', text)) 
super (_BufferMapping, self).__init__ ({ 
        COMMAND : Buffer (complete_while_typing = True, completer = create_command_completer (_handle_command), accept_action = AcceptAction (handler = _handle_command), auto_suggest = AutoSuggestFromHistory ()), 
        PROMPT : Buffer (accept_action = AcceptAction (handler = _handle_prompt_command), auto_suggest = AutoSuggestFromHistory ()), 
}) 

    
    

    Fix the buggy line: COMMAND : Buffer (complete_while_typing = True, completer = create_command_completer (_handle_command), accept_action = AcceptAction (handler = _handle_command), auto_suggest = AutoSuggestFromHistory ()) ,
assistant
