Any idea why I get the following:

DagsterStepOutputNotFoundError

When performing this action inside of an Op? I’m on 1.4.5 and python 3.10.6

yield AssetMaterialization(
        asset_key="redaction_log",
        description="Redaction Logs",
        metadata={
            "preview": MetadataValue.md(preview_df.head().to_markdown()),
            "description": MetadataValue.md(result.describe().to_markdown()),
            "raw_count": len(result),
        }
    )

happens to us all 🤷
