Prefect Community

Hi everyone, is there an example of how to manually set the state of a flow or task to failed in prefect 2?

• The UI
• The CLI
• From another flow or task
• From within the flow or task

From within the flow or task, both would be useful

```import prefect
from prefect.states import Failed


@prefect.flow
def foo():
    bar()


@prefect.task
def bar():
    return Failed(message="Oh no!")


foo()```
