AttributeError: 'CheckpointInput' object has no attribute 'action'

I have a error:

Traceback (most recent call last):
  File "script.py", line 290, in <module>
    kcl_process.run()
    ~~~~~~~~~~~~~~~^^
  File "python3.14/site-packages/amazon_kclpy/kcl.py", line 296, in run
    self._handle_a_line(line)
    ~~~~~~~~~~~~~~~~~~~^^^^^^
  File "python3.14/site-packages/amazon_kclpy/kcl.py", line 275, in _handle_a_line

                      ^^^^^^^^^^^^^
AttributeError: 'CheckpointInput' object has no attribute 'action'

If we will see to kcl.py we will find a code like:

    def _handle_a_line(self, line):
        ...
        action = self.io_handler.load_action(line)
        self._perform_action(action)
        self._report_done(action.action)

Where action is amazon_kclpy.messages.CheckpointInput object.

If we go to amazon_kclpy/messages.py, we will find that

class CheckpointInput(object):
    ...
    def __init__(self, json_dict):
        ...
        self._sequence_number = json_dict["sequenceNumber"]
        self._sub_sequence_number = json_dict["subSequenceNumber"]
        self._error = json_dict.get("error", None)

    @property
    def sequence_number(self):
        ...

    @property
    def sub_sequence_number(self):
        ...

    @property
    def error(self):
        ...

here is really no action property.

Sounds like it should be fixed
