Hello Community, I am running into a snag and I was wondering if anyone had any insight on what is going on. It appears my flow is getting stuck in the
Submitted for execution:
phase. I am using
storage (The image is hosted in ECR and I’ve confirmed my execution role has access to the repo) and
. The flow runs locally but not in ECS. Dockerfile:
Copy code
FROM prefecthq/prefect:latest-python3.8
WORKDIR /opt/prefect
COPY requirements.txt .
RUN pip install --upgrade pip && \
    pip install --no-cache-dir -r requirements.txt
Flow code:
Copy code
import os
from prefect import Flow, task
from prefect.run_configs import ECSRun
from prefect.storage import Docker

def extract():
    x = [4, 5, 6]
    print("Starting: {}".format(x))
    return x

def transform(y):
    return [i * 10 for i in y]

def load(z):
    print("Received: {}".format(z))

with Flow("Test Flow", storage=Docker(dockerfile="Dockerfile", registry_url=os.getenv("REGISTRY_URL"), image_name=os.getenv("IMAGE_NAME"))) as flow:
    e = extract()
    t = transform(e)
    l = load(t)

flow.run_config = ECSRun(
Hey @Jacob Wilson, unfortunately there is not much that we can get out of this. You need to attach a CloudWatch log group to the task definition of the Flow so that you get ECS logs on CloudWatch and can figure out what the issue is
