  1. 1To resolve this issue, follow these steps:
  2. 21. Check the schema configuration: Verify that the schema map is up-to-date and accurate.
  3. 32. Update the schema mapping: If the schema has changed, update the mapping to reflect the new schema.
  4. 43. Check for naming conflicts: Ensure that there are no naming conflicts between tables or databases.
  5. 54. Review configuration files: Verify that the configuration files are correct and not outdated.
