THEN In the _load_checkpoint_tuple method, replace direct unpacking of channel_values with a safe fallback: get the value from the checkpoint dict and default to an empty dict if None. For example: checkpoint_channel_values = value["checkpoint"].get("channel_values") or {}. Then use **checkpoint_channel_values. This prevents the None-type error while preserving existing behavior for valid data.

checkpoint_channel_values = value["checkpoint"].get("channel_values") or {}
"channel_values": {
    **checkpoint_channel_values,
    **self._load_blobs(value["channel_values"]),
}
