Azure Analysis Services Perspectives not Returning Data

[amfailor]

When we connect to our Azure Analysis Services instance in Power BI Desktop and PowerBI.com, everything works if you are going through the default perspective, but if any perspective is chosen, no data is returned and an "Unexpected Error" is given. This is breaking every report we have, because they are all using AAS.

Example:

Couldn't retrieve the data for this visual. Please try again later.
Please try again later or contact support. If you contact support, please provide these details.

@amfailor ,

Please check if any data column type or name has been changed in ssas model.

We are also experiencing this problem. No change on the AS model. Can connect to the default model but can't connect to any perspective.

@amfailor Microsoft are suggesting that this may be caused by a service upgrade late last week.

This is not SSAS. We are using Azure Analysis Services which had an update released the night before we started seeing issues.

I've recreated this issue on 2 servers for 5 different models for 5 different people. Nothing has changed to any of the models.

@amfailor This is a legit bug. A client of ours ran into the issue and submitted a support request. MS support and the product team are aware of the issue, but it sounds like a fix may be a few days or more away.

Thanks for the comment @Meagan 

We have a ticket open with Microsoft support.  Took 4 or 5 days for a confirmation of what we thought was happening, but they do appear to be working on it now.  Hopping for a quick(ish) resolution. This has taken down the majority of our company's reports, unless we redeploy every single report individually, which we'd have to change back once it is fixed. Not really feasabile when we have hundereds of reports relying on AAS models.
