Troubleshooting

​
Workflow Deployment Error

If there were any errors during the workflow deployment process, the Ingestion Pipeline Entity will still be created, but no workflow will be present in the Ingestion container.
  • You can then Edit the Ingestion Pipeline and Deploy it again.
  • From the Connection tab, you can also Edit the Service if needed.

​
Connector Debug Troubleshooting

This section provides instructions to help resolve common issues encountered during connector setup and metadata ingestion in OpenMetadata. Below are some of the most frequently observed troubleshooting scenarios.

​
How to Enable Debug Logging for Any Ingestion

To enable debug logging for any ingestion workflow in OpenMetadata:
  1. Navigate to Services Go to Settings > Services > Service Type (e.g., Database) in the OpenMetadata UI.
  2. Select a Service Choose the specific service for which you want to enable debug logging.
  3. Access Agents Tab Go to the Agents tab and click the three-dot menu on the right-hand side of the ingestion type, and select Edit.
  4. Enable Debug Logging In the configuration dialog, enable the Debug Log option and click Next.
  5. Schedule and Submit Configure the schedule if needed and click Submit to apply the changes.

​
Permission Issues

If you encounter permission-related errors during connector setup or metadata ingestion, ensure that all the prerequisites and access configurations specified for each connector are properly implemented. Refer to the connector-specific documentation to verify the required permissions.

​
Databend-Specific Issues

The following issues are specific to the Databend connector.

​
Test Connection Fails Against a Non-TLS Endpoint

The default self-hosted Databend port 8000 serves plain HTTP. If the connection test fails, open Advanced Config, add sslmode under Connection Options, and set it to disable. For a TLS endpoint, set sslmode to enable.

​
Test Connection Fails on a Specific Step

The test runs these steps: CheckAccess, GetDatabases, GetSchemas, and GetTables are required, and GetViews is optional.
  • CheckAccess: OpenMetadata can’t reach or authenticate with Databend. Confirm Host and Port, Username, and Password.
  • GetDatabases: OpenMetadata can’t access the Databend default catalog.
  • GetSchemas: The user can’t list Databend databases.
  • GetTables: The user can’t list tables in a Databend database. Confirm the user can read information_schema metadata.

​
No Schemas or Tables Are Ingested

OpenMetadata excludes the information_schema, system, and system_history databases by default. Leave Database Schema blank to scan all other accessible databases, or set it to restrict ingestion to a single database. Review your filter rules in the What to Ingest step, and confirm the user can read the databases you expect to ingest.
