No such channel: 'control'

I am getting this error on my jupyter logs.

[W 2021-07-30 18:22:03.947 ServerApp] No such channel: 'control'

I believe it is preventing me from loading the ipykernel debugger despite have lab 3.1.1 and ipykernel 6.0.3. See Missing Debugger Option

Can anyone advise as to why I am seeing the missing ‘control’ channel error?

My full package list is below. Note I am not running in a conda or any virtual environment. I am running in a docker image that I built from scratch using the jupyter docker stacks as a model (needed to remove package bloat for my deployment)
