Was it connected to SSAS? If you have "Live connection" set up people viewing the dashboard must have access to the data source, please refer to Manage your data source - Analysis Services - Power BI | Microsoft Docs

You can use "import" instead and scheduled refresh to avoid this.

"An unexpected exception occurred." That's rather not helpful.  

Anyway, please provide more context.

Assuming you have a PRO license - you can submit tickets to Microsoft from the support page.
