After you restore a backup to the Tableau Server, some workbooks that use extracts show the following error message:
Tableau Data Engine Error 4: Invalid Command: database: Path does not exist. Unable to connect to the server <primary data engine IP>.
Extract refreshes for these workbooks may fail with the same error, or with the following error message:
java.lang.RuntimeException: Process extracts errorWhen you check the backup file, some of the extract files are missing.
No extracts to refresh for Workbook: '<workbook name>'
Views based on live connections work as expected.
