dagster

I'm trying to use a resource within a sensor just like in the <https://docs.dagster.io/concepts/partitions-schedules-sensors/sensors#using-resources-in-sensors|docs here>, but I'm getting `dagster._core.errors.DagsterImportError: Encountered ImportError: cannot import name 'Definitions' from 'dagster'` Is `Definitions` not available in dagster version 0.15.8?

that's correct. it was introduced post-Dagster-1.0

You might be able to use `build_resources` inside your sensor: <https://docs.dagster.io/_apidocs/resources#dagster.build_resources>
