Hello I am trying to set up metaflow in AWS but when I run terraform plan I get a message that "An argument named "ui_allow_list" is not expected here." I checked the read me on both github landing page and the UI module page and ui_allow_list is an acceptable option. Any insights how I can get past this ? If I remove that argument it works but I want to configure the UI to watch the workflows. I am a first time user of Metaflow. So, I could be missing something
