Error messages

Running a query can respond with errors.

The errors can be caused by either the user or by a Data Fabric response from the services utilized in the Compass user interface.

Different scenarios can respond with an error message, such as:

  • Connection issues to service
  • Query syntax error
  • Invalid objects and properties
  • Invalid use of functions
  • Service errors

For more details on the error messages and scenarios, see Troubleshooting Compass queries.

When an error occurs, it is displayed in the Results panel with this structure:

  • Error reason and error code
  • Message describing the error
  • Query ID that can be referenced for support
  • UTC date and time when the error occurred

The error message can be copied to the clipboard to provide full and complete error references.

When the graphical interface fails to communicate with one of the backend services, such as Data Catalog or Compass backend service. The respective panels where the service is used, indicate the error state. If communication with Data Catalog cannot be achieved, the left Data Objects panel does not show any objects and displays a message.

If communication with the Compass backend service cannot be achieved, the results are not displayed, and the Result panel displays a message.
