Deployment Pipelines

I was trying to do the reverse Deployment Pipe starting with Promoting the Existing premium capacity workspace as a Production Workspace however I am getting an error 

Is there a way to get an indicator saying how many items inside the workspace met/not met the conditions stated in the MS document? Unfortunately, it gives only the generic message so far. Worst case scenario is I need to go to the workspace and check the items inside 1x1. Which definitely takes time to complete
