Hello everyone, I’m currently setting up a deployment that includes an ECSTask infrastructure block and an S3 storage block. To customize the ECSTask, I’m using a custom docker image with the dockerfile below So, my question is: What is missing from my Dockerfile image or Deployment object so it retrieves the flow correctly from the downloaded files in the S3 storage? Thank you in advance for any help you can provide.

I would try adding

fsspec==2023.1.0

to your

pip install

line. It looks like fsspec 2023.4.0 is included in the latest

prefecthq/prefect:2-python3.10

image build, and it reportedly causes the

FileNotFound

problem: https://github.com/PrefectHQ/prefect/issues/9262 That issue is about Azure storage, not S3, but the S3 and Azure blocks both use

fsspec

. You could also try

S3Bucket

storage from the

prefect-aws

collection, because it doesn't use

fsspec

at all: https://prefecthq.github.io/prefect-aws/blocks_catalog/#s3-module

Thanks for your suggestions @Ryan Peden! I just did a test running a simple flow with the default prefect image and was getting the same error. So I read online that adding

path=""

to the deployment can help fixing it and it indeed worked! I’m trying now with my own image, but seems like this was the error.

thanks for sharing the solution! I'm glad to hear it worked
