ValueError: badly formed hexadecimal UUID string

[r-bt]

Hi,

I'm trying to use this library with a Sphero Bolt. I'm on macOS using python 3.10

from spherov2 import scanner
from spherov2.sphero_edu import SpheroEduAPI

toy = scanner.find_toy()

I get the following error:

Exception in callback CentralManagerDelegate.did_discover_peripheral(<CBCentralMan...x600003ff0d80>, <CBPeripheral... disconnected>, {
    kCBAdvD...erLevel = 8;
}, -97)
handle: <Handle CentralManagerDelegate.did_discover_peripheral(<CBCentralMan...x600003ff0d80>, <CBPeripheral... disconnected>, {
    kCBAdvD...erLevel = 8;
}, -97)>
