CDS not working and response with error message also dose not contains data in entities

CDS not working and response with error message 

The requested operation is invalid. Server Response: {"error":{"namespace":"ServicePlatform","code":"UnknownError"}}



I figured out the problem

There are issues with the CDS in the environment in the Europe Region.


when I create an environment in United State region and create a new database the CDS working perfectly,

but when using environment in Europe Region where our database and entities created there are issues we cannot figure out  

Where can we check the availability of the CDS in particular region where the environment has been created?

What’s your current situation? Are you still having the issue?

To test this issue, I create an environment in Europe region, I don’t get any issues when working in this environment, I can create entities and add fields in the entities, also create apps based on entities.

Please check it again. I assume that it might be a temporary issue when there are some updates on PowerApps.

If you are still having the issue, please feel free post back.

Still, We had the same issues,


Maybe you are not facing any issue with your environment,

But our environment  in Europe region has some issues, we already create custom entities and also we create a PowerApps  with CDS connection in that environment and it was working until 20th September 2017,

After that, as we posted all data lost in our custom entities, not able to export the template from the entities.


we open a ticket with the Microsoft team.
