Error parsing combo descriptor

Commencez par le constructeur Python Descriptor affiché dans la trace d’erreur et reproduisez le snippet de combo descriptor fourni. Suivez la façon dont le constructeur traite la chaîne du descriptor et déterminez si les combo descriptors sont pris en charge ; le travail est terminé lorsque le comportement est clarifié et que le problème de parsing de l’issue est résolu ou documenté.

When initialising a combo descriptor this error was raised:

bdkpython.bdk.DescriptorError.Miniscript: error_message='unexpected «combo(1 args) while parsing Miniscript»'

Is this a legitimate error with the descriptor?

Code

from bdkpython.bdk import Descriptor, Network

TEST_NETWORK = Network(1)
DESC = "combo(tpubD6NzVbkrYhZ4YSPGUiT67AZRVmJUjPn1Twt4JuYPrkGZiwVKyBofjVRej8A194X2X4Toyo22HSaJJYLH2g4gd2JGnztsKzShiRFwWgAYi5D/0h/0h/*h)#leqp7cnz"

my_desc = Descriptor(descriptor=DESC, network=TEST_NETWORK)
