transaction has not been signed correctly

[kirito-cwx]

I can place order to a delegated account ,but came across the following error when cancel the order, anyone ever met with this or have ideas about this error?
raise AttributeError("transaction has not been signed correctly")
AttributeError: transaction has not been signed correctly

await drift_client.cancel_order(order_id=2)

you need to pass the authority of the account the delegate is running on to driftClient

if delegate key is Y
and delegated account is X
authority here should be X

example here:

driftpy/examples/limit_order_grid.py

Line 248 in d167ce1

parser.add_argument("--authority", type=str, required=False, default=None)
