Question

Hey I have a flow with manual task I added a state handler in order to post a Slack Message in a channel to let know that a task is waiting for approval Is there a way to print some kind of link to the task is running

Did the state handler not fire Can I see it

Santiago Gonzalez · Answer

Yeah the state handler is being triggered But I wanted to print in slack a link to the current execution if there is a way

You can make a state handler like <http def 20post to slack on failure task 20old state 20new state 20 20 20 20 20if 20new state is failed 20 20 20 20 20 20 20 20 20if 20isinstance new state result 20Exception 20 20 20 20 20 20 20 20 20 20 20 20 20value 20= 20 ``` ``` format repr new state result 20 20 20 20 20 20 20 20 20else 20 20 20 20 20 20 20 20 20 20 20 20 20value 20= 20cast str 20new state message 20 20 20 20 20 20 20 20 20msg 20= 20 20 20 20 20 20 20 20 20 20 20 20 20 20f The 20task 20` prefect context task name ` 20failed 20 20 20 20 20 20 20 20 20 20 20 20 20 20f in 20a 20flow 20run 20 prefect context flow run id 20 20 20 20 20 20 20 20 20 20 20 20 20 20f with 20an 20exception 20 value 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20SlackTask message=msg run 20 20 20 20 20return 20new state|this> and used the paused state and fire a message using the SlackTask instead It s configurable ```from prefect engine state import Paused def post to slack on failure task old state new state if isinstance new state Paused SlackTask message=msg run return new state```

And then you can pull the task run id and stuff from the context `prefect context get task run id ` to construct as URL to include in the message
