Error while setting up ue_smart_radio platform for media_player

Hello,
I have the following errors when trying to setup the smart radio:

Traceback (most recent call last):

    await asyncio.wait_for(asyncio.shield(task), SLOW_SETUP_MAX_WAIT)

    raise KeyError('name=%r, domain=%r, path=%r' % (name, domain, path))
KeyError: "name='sdi_squeezenetwork_session', domain=None, path=None"

Many thanks for your help.
