Quick Question About the built in, well I suppose, chatbot or LLLM Assistant

I hope it is not against any rules of the group, just a quick question i am hoping someone can answer me and save me a lot of time researching - not sure why i keep getting this error, the group of lights is clearly labeled (please see the screenshot). I am fairly new to home assistant, but I started to use smart home products around 2013...Any advice is much appreciated - thank you!
