Question

Hi wave I am using `prefect tasks prefect create flow run` to kick off some tasks I ve noticed that this isn t returning an id for the flow run as documented and instead returning a `Task` object Any advice on how to access the ids of created runs

Kevin Kho · Answer

Hi < Jacqueline Riley Garrahan> can you show how are you using it Are you using it inside a Flow

Jacqueline Riley Garrahan · Answer

```with Flow schedule run as flow flow run id = create flow run flow name=flow name project name=project name parameters=data ```

Jacqueline Riley Garrahan · Answer

Yup

Kevin Kho · Answer

This looks right How are you trying to use the `flow run id`

Jacqueline Riley Garrahan · Answer

I d like to poll for completion of the task

Jacqueline Riley Garrahan · Answer

```prefect tasks prefect flow run get task run result flow run id ```

Kevin Kho · Answer

`get task run result` is meant to be on a task level inside the `flow run id` Do you want `wait for flow run` instead

Thank you

Jacqueline Riley Garrahan · Answer

< Kevin Kho> if using wait for flow run can I get the result from the run

Kevin Kho · Answer

You have to use the `get task run result` but that is a specific task inside the subflow You should find an example <https www prefect io blog prefect 0 15 0 a new flow run experience |here>

Do I need to define a slug for tasks

Jacqueline Riley Garrahan · Answer

```ValueError No task runs found while querying for task runs where task slug eq create some data 1 flow run id eq 601f6e54 b2fb 4119 b9c3 1faaf0a00205 map index eq 1 2022 02 18 12 02 16 0800 INFO prefect TaskRunner | Task get task run result Finished task run for task with final state Failed 2022 02 18 12 02 16 0800 INFO prefect FlowRunner | Flow run FAILED some reference tasks failed ```

Kevin Kho · Answer

There is a default slug created but you can do The `slugifying` is kind of aggressive so it happens stuff like 1 or copy sometimes The API is the best way to get the slug I m not sure if it s in the UI

Jacqueline Riley Garrahan · Answer

Could you give example Trying to access like this doesn t work as the slug is None

Jacqueline Riley Garrahan · Answer

```with Flow schedule run as flow flow run id = create flow run flow name=flow name project name=project name parameters=data need slug child data = get task run result flow run id flow run id slug ```

Kevin Kho · Answer

Ah actually I think if you do `print flow serialize ` on the subflow side you can see the task slug it was registered with in there

Kevin Kho · Answer

Or this to be cleaner `print flow serialize tasks `

Kevin Kho · Answer

And look for the `slug` entries to get the slug
