<@U05NDLFDWPK> Would you mind sharing how you purged? We are having the exact same issue. Specifying the CLI version doesn’t work. Removing all the metadata by CLI command datahub -delete --env PROD --hard --force and datahub -delete --entity-type container --hard --force but no vail.
<@U05HUB7E31U>, sorry for delayed response. I deleted all datasets first with datahub delete --entity-type dataset --hard and then removed all platforms with datahub delete --platform looker|dbt|bigquery|... --hard.
