[AmazonEchoControl] IllegalArgumentException when sending command

[felixschndr]

I added a light to my Amazon account to be able to control it via the AmazonEchoControl Binding in OpenHAB. This works just as expected normally. However this time I am facing the problem that I cannot control the color of a lamp.
All item values are populated properly. I can set the brightness of the lamp. I can read the color of the lamp. However setting it does not work:

This is the light, it's kinda cheap I guess but is Alexa certified and can be controlled as expected in the Alexa app. That's why I think it's not a problem with the lamp itself but the binding.

Steps to Reproduce (for Bugs)

1. Add lamp in Alexa app
2. Add lamp as thing Thing smartHomeDevice Amazon_Arbeitszimmer_Deckenlampe "Amazon_Arbeitszimmer_Deckenlampe"@"Deckenlampe" [id="SKILL_xxx"]
3. Create item Color AmazonArbeitszimmerDeckenlampeColor "Color"{channel="amazonechocontrol:smartHomeDevice:Amazon_System_Konto:Amazon_Arbeitszimmer_Deckenlampe:color"}
