# QuestDB Troubleshooting | OpenMetadata Connector

> Troubleshoot common QuestDB connector issues in OpenMetadata - connection failures, permission errors, and ingestion problems.

## 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 Ingestion Tab**
   Go to the **Ingestion 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.

## QuestDB-Specific Issues

### Connection Refused on Default Port

QuestDB listens on port **8812** for the PostgreSQL wire protocol - not the standard PostgreSQL port 5432. Ensure your `hostPort` is set to `<host>:8812` and that the port is reachable from the ingestion host.

### Schema Filter Not Supported

QuestDB operates as a single-database (`qdb`), single-schema (`public`) system. Schema filtering is not applicable - all tables reside in the `public` schema and will be ingested automatically. You can use `tableFilterPattern` to restrict which tables are included.
