beginner question: ECS terraform deployment; tasks are stuck in pending

Has anyone tried to deploy the terraform ecs templates and encountered the tasks being stuck in pending before? I am going to continue plugging away at it tomorrow but wanted to reach out to see if anyone had something similar.

the terraform for reference, copy and pasted from the docs with some roles manually made

Thanks!
