100 Days of AWS - Day 47 - unclear failure message

Hello, I’m getting faiilure at the lab check for this stage although seems for all stages to passed sucssfully. In addition the message is unclear - what could be the issue?

I’m not sure why you got that particular message. I worked from this solution, changing the names of the objects in the stack file to match the task description (since these names are randomized). This worked, and the grader accepted it.
