Hi @User I think this is some outdated docs. We recently moved our built in runners to inherit from a class called

AbstractRunner

which looks like it has a 3rd argument of

is_async:bool

. https://kedro.readthedocs.io/en/stable/_modules/kedro/runner/sequential_runner.html#SequentialRunner https://kedro.readthedocs.io/en/stable/kedro.runner.AbstractRunner.html So I think you need to tweak the example code in the docs for DryRunner to looks more like the constructor in SequentialRunner. I'll raise a ticket to fix the docs.
