Question

Is there a way to get the result returned by a flow triggered using client create flow run

Dan Kerrigan · Answer

Using the following code the state result is always None ```import time from prefect import Client task Flow client = Client task def dummy task return 42 with Flow meaning of life as flow life meaning = dummy task flow id = flow register flow run id = client create flow run flow id state = client get flow run info flow run id state while not state is finished print f state message Sleeping 5 time sleep 5 state = client get flow run info flow run id state print f Flow finished state message assert state is successful print f Result is None state result is None ```

``` Result check OK Flow <http localhost 8080 flow 015ce980 762a 48cf a864 1f9c5bafb2a8> Flow run scheduled Sleeping 5 Flow run scheduled Sleeping 5 Flow finished All reference tasks succeeded Result is None True```

Hello < Dan Kerrigan> Just to clarify a flow run will not return a result but a task run will So to grab any results from the flow run we d have to grab the results from the desired `task run` of your flow In this case we can do something like this ```from prefect import Client c = Client Getting task runs flow run = c get flow run info YOUR FLOW RUN ID task runs = flow run task runs Grabbing the location of a task s result in this case the first task in the list location = task runs 0 state result location Grabbing the result of a specific task based on location task runs 0 state result read location ``` I hope that makes sense let me know if we can clarify this to suit your provided flow
