Hey I'm new with Prefect and I have a small issue. Like I was able to run prefect inside a docker with as S3 Minio everything works fine, even I was able to trigger my flow run via an API call /api/deployments/{id}/create_flow_run. My flow:
Copy code
@flow(name="Run Check", description="Flow that controls the data integrity")
def run_check(layers_data):
    """
    1- Extract data from Arcgis databse
    2- Transform data
    3- Load result into Excel output
    @param layers_data:
    @return:
    """
    # 1- Extract data from  databse
    state = extract_data(layers_data, return_state=True)
    raw = state.result()
    # 2- Transform data
    state = DataTransformer.transform_results(raw, return_state=True)
    data = state.result()
    # 3- Load result into Excel output
    state = DataWriter.load_results(data, return_state=True)
    output = state.result()
    return {"Result": {
        "nb_errors": 12,
        "nb_lines_checked": 456
    },
        "output_path": "path_to_s3"
    }
My question is how to get the results returned by my flow run like I want to get
Copy code
{
  "Result": {
    "nb_errors": 12,
    "nb_lines_checked": 456
  },
  "output_path": "path_to_s3"
}
I used the Endpoint :/api/flow_runs/{id} But I I dont the my result in the response 😕 Any help ? Any idea . I thought about saving the result in the S3 bucket than retrieve it but not sure if this is the best practice Thaaaaaaaaaaaanks in advance

I’m not exactly sure what you mean by
get the results
-- If you don’t need to pass the data somewhere else, but you’re just wanting to view the results in the UI you could use logging https://docs.prefect.io/concepts/logs/?h=logging

I mean I need to pass the data to somewhere else. I have a microservice that calls the Prefect API to trigger a flow and that waits for a response

Hi Seif, in that case I think this might be helpful for you https://docs.prefect.io/concepts/results/#toggling-persistence
