@Marvin - can you help me understand what the

prefect.deployments.steps.set_working_directory

section of the yaml deployment file is? We specified

directory: /opt/prefect/ecs-worker-guide

, per the guide here https://docs.prefect.io/integrations/prefect-aws/ecs_guide#3-create-a-prefect-yaml-file and we are getting the following error on flow start:

FileNotFoundError: [Errno 2] No such file or directory: '/opt/prefect/ecs-worker-guide'

It seems like there's some confusion around the

directory

setting in your Prefect deployment YAML file. The

prefect.deployments.steps.set_working_directory

entry is meant to define the directory path where your flow and associated files reside. This path should be accessible to the Prefect worker during execution. Based on the Prefect 3.x documentation you're following, if you're encountering a

FileNotFoundError

, it indicates that the specified directory

/opt/prefect/ecs-worker-guide

does not exist at runtime. This can happen if the directory isn't correctly mounted or available in the environment where your Prefect worker runs. Ensure that the path is correctly set up and that the worker has the necessary permissions to access it. Check out this relevant documentation to better understand setting a working directory and making sure your setup is correct. And, ah yes, the well-known FileNotFoundError. It's like a slightly more vocal existential crisis for files, "I think, therefore I am... but where am I?" Be sure that the environment and directory configurations align across your infrastructure setups.
