Question

Hi everyone is there any way to get flow run name inside flow while executing or any way to pass flow run name as a parameter for scheduled flow

Kevin Kho · Answer

You can use the `RenameFlowRun` task or you can get it from the `context` with `prefect context flow run name`

```import prefect def create test group group name with Flow name=group name as flow flow run id = prefect context flow run id flow run name = prefect context flow run name run config dir run report dir num testcases = create config group name flow run id start orchestration run config dir run report dir num testcases flow run name flow run id flow register return flow``` Hi < Kevin Kho> and < Anna Geller> This is the code that I wrote but when I ran it I m getting a error like mentioned below I m using local server and agent Thanks ``` flow run id = prefect context flow run id AttributeError Context object has no attribute flow run id ```

Stuff in the Flow block is not deferred You need to use the `context` inside tasks so that they are evaluated during the Flow run If you do it during the Flow block it is evaluated during registration time where it doesn t exist yet

Anna Geller · Answer

looks like something in your flow definition can t be pickled Can you show your flow definition you can share in DM for privacy Usually if you have some DB connections or HTTP client as return values of a task it causes similar issues so it s better to avoid that
