EB CLI . ERROR: TypeError - 'NoneType' object is not subscriptable

I'm currently learning an AWS Cloud Developer Nanodegree on Udacity. In one of the videos where I have to use eb cli to create an environment, I run into an error when following the prompt. I have attached an image of my config.yml and my terminal. Please is there anything I might have overlooked? Thanks for the help I use Ubuntu 22.04
