why do i need this. I have state_handler for notification in slack when flow is failed. and i want have sm like this

msg = (
            f"Hey <@{prefect.context.flow_owner}>\n"
            f"Run `{prefect.context.flow_run_name}` of flow `{prefect.context.flow_name}` "
            f"entered `FAILED` state with message `{state.message}`."
            f"See {prefect.context.flow_run_link} for more details."
        )

for personal notification. And I want move this handler in our lib and don’t write this handler in every file

@Marko Herkaliuk the state handler can be defined in some custom module, and the context values will still be filled based on runtime values - so you can move it to your custom library

last point: flow_run_link could be constructed this way:

f"<https://cloud.prefect.io/{your_tenant}/flow-run/{flow_run_id}>"
