Thank you for using the Tableau Support Community!
The error you are seeing is generally due to the Tableau Extract Refresh Utility not being able to connect to the data source. One of the following troubleshooting steps might resolve this issue:
- Remove the @<data source provider>.com part of the username from the --source-username option in the command.
--source-username <username>@<data source provider>.com
- Verify that all the fields necessary to connect to the data source are included in the command-line script, including --source-username and --source-password.
- Verify that the computer running the command has permission to access the file path specified for --original-file.
- Verify that the --original-file path is using the server name and not the drive name. For example, the command should begin with \\<servername>\ rather than D:\.
I hope the information above helps, but if not, please let us know!
