@Marvin I am having trouble with the following code:

from prefect import flow, get_run_logger
from prefect_aws.s3 import S3Bucket

if __name__ == "__main__":
    flow = flow.from_source(
        source=S3Bucket.load("s3-storage-block"), entrypoint="FILE_PATH:flow_function"
    )
    print(flow)
    flow.deploy(name="test-deploy-s3", work_pool_name="local-pool")

The code is not able to move past the flow.from_source part. However, if I try the following approach, it works:

s3_bucket = S3Bucket.load("s3-storage-block")
with open("LOCAL_FILE", "wb") as f:
    s3_bucket.download_object_to_file_object("FILE_PATH", f)

It successfully downloads the file from S3, but getting the flow from S3 does not work Could you please help me understand why the flow.from_source part is not working and how I can fix it? Using Prefect3

It appears that your issue with

flow.from_source

and S3 may be related to a bug or a limitation where the dependencies for the flow need to be present in the environment. Here are a few crucial points: 1. Dependencies Issue: The flow's dependencies must be present in the environment where

flow.from_source().deploy()

is executed. If there are missing modules in your S3 bucket (as highlighted in the issue https://github.com/PrefectHQ/prefect/issues/14464), the flow cannot be created from the source. 2. Alternative Method: You can manually download the file from S3 (as in your second example) and ensure that all dependencies are present locally. Then, call

flow.deploy()

. 3. Using Remote Storage: The use of

RemoteStorage

can help if your dependencies are spread out. The Prefect documentation and issues indicate improvements in handling storage blocks. You can refer to this document. 4. Advanced Configurations: Prefect has improved support for remote sources and various storage solutions. Refer to this guide for additional approaches. For now, I would recommend ensuring that your environment has all the necessary dependencies and avoid relying solely on the

flow.from_source

if the dependencies are complex. Here are some more relevant links: - Issue regarding missing dependencies - Added support for storage blocks I hope this helps you troubleshoot the problem more effectively.

I dont get any type of error the code just stays running for several minutes without no response
