Capabilities download workflow warehouse-release-download-################################-tas-hub-collector-10.4.0 has unexpected status FAILED" is returned during the attach workflow in Tanzu HUB GUI.Tanzu Hub 10.4 air-gapped.
This failure occurs because the hubDocumentServiceTtlSeconds value set in the download manifest file during Step 2 of this KB has been reached. When this timeout value is reached, Hub automatically removes the products that were manually uploaded, leading to the failure in download workflow during attach operations. Step 2 of the reference KB notes this:
NOTE: The TtlSeconds hubDocumentServiceTtlSeconds: 2628000 configures this to hold the product for 30 days in Tanzu Hub. These products will be automatically removed from Hub and will require this manual process be run again if the TtlSeconds expire.
Run the Manual download and upload of the desired products again using the steps detailed in this KB.
