Failed to coerce argument 'room_numbers' to list[int]: Unsupported annotation: list[int]

[lemorage]

Describe the bug
My tool definition:

def create_a_staging_order_for_booking_a_room(
    user_id: str,
    user_name: str,
    user_contact: str,
    check_in_date: str,
    check_out_date: str,
    num_of_guests: int,
    room_numbers: list[int],
) -> dict[str, dict]:

I have a tool shown above, attached to an agent. When this agent executed this tool, I got the error message saying:

  "message": "Error executing function create_a_staging_order_for_booking_a_room:
              ValueError: Failed to coerce argument 'room_numbers' to list[int]: Unsupported annotation: list[int]"

What happens if you do List[int]?

It will show error msg like that instead :(

"Error executing function create_a_staging_order_for_booking_a_room:
