Hi everyone, I did not find anything related to my problem so here I am.

I want to create an asset sensor for an asset loaded from my dbt project which waits for its upstream Fivetran dependency to materialize. Given my dbt asset key, I can not figure out how to obtain the upstream asset key I need for the asset sensor declaration. So far I was messing with the AssetSelection class and managed to obtain the upstream (`AssetSelection.keys(AssetKey([prefix, name])).upstream()`) but I can not find how to get the corresponding asset keys. Thanks for your help :pray:

Hi Alexis. If you're using a `multi_asset_sensor`, you can directly pass in an `AssetSelection` like this:

`multi_asset_sensor(monitored_assets=AssetSelection(...)`

If you're using an `@asset_sensor`, you will have to resolve your asset selection by doing something like:
```@asset_sensor(asset_key=AssetSelection(...).resolve(defs.get_repository_def().asset_graph)[0])```


Though ideally we allow you to pass in an asset selection into that argument as well
