How do I create an AssetSelection of my dbt assets using dbt tags?

[dagsir[bot]]

Hello! I am strking out on resources for this. I am looking to convert a dbt_asset definition to a job. The trick is, I want the job to match the dbt tag definition in the dbt_asset construction. I can't seem to find the AssetSelection call that will translate that properly. I have more dbt assets in my group that I originally built out that I want to be called in a second job. I really don't want to manage this all through both dbt tags and groups matching 1:1.

The question was originally asked in Dagster Slack.

You can build an AssetSelection of dbt assets using build_dbt_asset_selection. This creates a DbtManifestAssetSelection that defines a selection of assets from a dbt manifest and a dbt selection string.

Hi @rexledesma
foo_selection = build_dbt_asset_selection([dbt_assets], dbt_select="tag:foo")
The line above is giving the following error.
lib/python3.10/dist-packages/dagster_dbt/asset_utils.py", line 305, in get_manifest_and_translator_from_dbt_assets
metadata_by_key = dbt_assets_def.metadata_by_key or {}
AttributeError: 'list' object has no attribute 'metadata_by_key'
