This unpacking will fail with a ValueError: not enough values to unpack when encountering untyped dict fields (e.g., device_status: dict | None at line 242 in this file). For untyped dicts, get_args(dict) returns an empty tuple ().

Consider adding a check for this case:

args = get_args(class_type)
if not args:
    # Untyped dict - no conversion needed
    return value
key_type, value_type = args
Suggested change
key_type, value_type = get_args(class_type)
args = get_args(class_type)
if not args:
# Untyped dict - no conversion needed
return value
key_type, value_type = args
