If you're seeing an empty folder when you navigate to the workspace folder, it's possible that you may not have the necessary permissions to access the data flow.
- Ensure that you have the necessary permissions to access the workspace where the data flow is located. You can check this by going to the Power BI website and navigating to the workspace where the data flow is located. From there, click on "Access" and make sure that your account has the necessary permissions.
- If the issue persists, you can try creating a new data flow in the Power BI website and then accessing it from Excel. This can help to rule out any issues with the original data flow.
