core: Vesync integration is not returning any devices

The problem

Hi!

I have a Levoit Core 200s and wanted to use the Vesync integration since I have been controlling the device via the Vesync app. When I login to the integration, nothing happens. The integration does not pull in the device.

I tried adding the raw github code from HA core as a custom component and added some additional logging. When it runs manager.update, it returns zero devices. I tried forcing it via manager.get_devices and received the error below.

I’m not sure if this is an API error, an issue with the pyVesync library or its integration with HA. I don’t receive a login error and running manager.enabled returns true, so it looks like it’s accepting my credentials.

What version of Home Assistant Core has the issue?

core-2021.11.5
