login-qr issue

Traceback (most recent call last):

    timeout = (self._resp.expires - datetime.datetime.now(tz=datetime.timezone.utc)).total_seconds()
AttributeError: 'LoginTokenMigrateTo' object has no attribute 'expires'

When I issue the login-qr command a QR code is generated but I'm unable to actually login due to the above error.

Any suggestions?

I am running the latest version of Synapse and the latest version of mautrix-telegram with the latest container tags.
