From the log of the wait containers in those pods and the annotations it looks like this messages_to_be_sent.json is the output of that pod.

Together with the fact that the number of messages to be sent is 0 maybe the process tried to reread the file it writes, and fail when it did not write it because there was no messages ?

I'll take a look.

Hum, it's not as bad as it looks.
We just log it wrong :

    # Store message to file that need to be sent.
    try:
        with open(MSG_OUT_FILE, "r") as json_file:
            if os.stat(MSG_OUT_FILE).st_size != 0:
                all_messages: list = json.load(json_file)
                if type(all_messages) != list:
                    raise TypeError(f"Message file must be a list of messages. Got type {type(all_messages)}")
                all_messages = all_messages + output_messages
    except Exception as e:
        _LOGGER.exception(e)
        all_messages = output_messages

_LOGGER.exception is _LOGGER.error with extra stuff. This should probably be more specific and not and error.
