AttributeError: 'NoneType' object has no attribute 'status_code'

Apologies if this has already been raised (I’ve searched other issues and couldn’t find this error) or if this is just me being an idiot but I had the ‘camera’ working fine but I’m now seeing the below errors - Any ideas what might be causing this?

Errors:

The username, password & token are all correct as I can still use the vacuum via the Xiaomi Mii integration.

Thanks in advance! 😃
