Hello is it possible to dynamically set which `project` a `create flow run` call creates a Flow for depending on environment variables Example in thread

Wesley Jin · Answer

project name is parameterized by environment we d like to run this Flow in ```with Flow example flow as flow load task = run reporting flow = create flow run flow name= Example Reporting Flow Name project name=f reporting os getenv ENVIRONMENT task args=dict trigger=all successful run reporting flow set upstream load task ```

after pushing code up to Github our Flow storage mechanism amp registering it successfully using CI w the appropriate env vars set running into ```KeyError Task slug create flow run 1 is not found in the current Flow This is usually caused by a mismatch between the flow version stored in the Prefect backend and the flow that was loaded from storage n Did you change the flow without re registering it n Did you register the flow without updating it in your storage location if applicable ```

You can if you wrap that f string as a task The problem here is that the f string is evaluated as the DAG is constructed not during flow run time

gotcha i ll try that when exactly does DAG construction happen still confused why there s a mismatch since the `ENVIRONMMENT` in CI registration amp the execution environments are the same

Kevin Kho · Answer

`with Flow ` constructs and than you do either `flow run ` or `flow register ` but if you don t call it that s why nothing runs It just gets built

Wesley Jin · Answer

thanks for the context Kevin the error I was running into before was actually on the CI side where the incorrect github storage `ref` was being set a branch that didn t have the `create flow run` call in the Flow was being referenced at Flow run time

Glad you figured it out
