Thank you so much Ryan! That worked wonderfully, thank you so much. I have another related question: I can't seem to find that block when attempting to deploy, i.e. with a command like

prefect deployment build flows/first_flow.py:hi -n dev -q dev -ib ecs/first-ecs-test -sb s3/first-flow -a

I get the attached error. am I using this block properly?

I think the name would be

ecs-task/first-ecs-test

, but to check for sure you can run

prefect block ls

to see the the slug for all blocks you've created.

that did it, thank you so much!
