metadata.overview does not propagate to Knowledge Catalog

[rosalindkng]

Background

According to the Dataform documentation, the metadata property can add metadata to a table in Knowledge Catalog.

For example:

config {
  type: "table",
  metadata: {
    overview: "This table provides standardized trip data."
  }
}

Steps to reproduce

1. Define a Dataform table with a non-empty metadata.overview value, as shown above.
2. Execute the workflow:
   • locally using dataform run; or
   • through the Dataform UI in Google Cloud Console.
3. Wait for the table and its Knowledge Catalog entry to be updated.
4. Open the table in Knowledge Catalog and inspect its overview metadata.

Expected behavior

Knowledge Catalog displays the value configured in metadata.overview:

This table provides standardized trip data.

Actual behavior

The table is created or updated successfully, but the configured overview is not displayed in Knowledge Catalog.

No error or warning indicating that metadata propagation failed is shown.

Environment

• Dataform Core version: 3.0.70
• Execution method: Local CLI and Google Cloud Dataform
• Google Cloud project region: US
• Repository region: US
• BigQuery dataset region: US
• First observed: August 31, 2026

Additional information

• Does the executing service account have the required Knowledge Catalog permissions? yes
• How long did you wait before checking Knowledge Catalog? 10 mins
• Does this also occur with a newly created table rather than an existing table? no
• Does other metadata, such as column descriptions, propagate successfully? yes

I see that it works as intended unfortunately:

• Dataform CLI doesn't support updating metadata in Knowledge Catalog yet, I'll add @rafal-hawrylak to triage it and find an assignee
• GCP Dataform doesn't yet support multi-regions like US, I'll add @SkyrimL to take a look here. I think we need to update public documentation to mention this limitation and take a look if it's possible to add support for multi-regions in GCP Dataform

I've already added this part of the issue on our backlog:
