Error in the variable explorer when inspecting variables generated by the Phue library

[JohnCanty]

Description

What steps will reproduce the problem?

Using Phue library installed in the working directory. perfrom a successful connect to the Hue lighting hub. Stored the lights in a dictionary using the ID as the Key.

lights = b.get_light_objects(mode='id')

Using the variable explorer I opened the entry that was associated with a lamp that is not RGB controllable.

switched mode to list, and a similar problem happens. I can create a separate bug for that is need be. Reproducible every time.

Please post a simple code sample that generates the problem above.

[JohnCanty]

from phue import Bridge
Brightness = 254

b = Bridge('10.10.11.2', 'APIKEY')

# If the app is not registered and the button is not pressed, press the button and call connect() (this only needs to be run a single time)
b.connect()

# Get the bridge state (This returns the full dictionary that you can explore)
b.get_api()

# Get the light information from the bridge and store it in a dictionary based on ID as the key.
lights = b.get_light_objects(mode='id')

for lightid,attribute in lights.items():
    print(lightid)
    print(attribute.on)
    print(attribute.brightness)
    if attribute.brightness >= 0:
        if attribute.on == False:
            b.set_light(lightid, 'on',  value=True)
            b.set_light(lightid, 'bri',  value=Brightness)
            b.set_light(lightid, 'on',  value=False)
        else:
            b.set_light(lightid, 'bri',  value=Brightness)

[JohnCanty]

This executes fine. But if I use the variable explorer to check out the dictionary that is created called 'lights'. The non-color changing lights in the dictionary cause this error.

Thanks for the code @JohnCanty! We'll try to fix this after we release Spyder 4.
