Exception occurred on the metadata service on client or server :D365

Exception occurred on the metadata service on client or server 

Exception occurred on the metadata service on client or server in Dynamics 365 Finance and Operations.

Problem :

Microsoft Dynamics 365 for Operations in VM. 

1. In Visual Studio 2015, I have created a new project and trying to customize an existing report.
2. I open the report. Go to the dataset and select "Query" as the "Data Source Type" in the properties window. Go to the Query property and click "..." to open the dialog. 
3. Select any Query and click next, I get the error "Exception occurred on the metadata service on client or server".

Solution

We have solved the problem.

When try to change Dataset on SSRSReports, VS try to call the following webservice https://yourURL.cloud.onebox.dynamics.com/Services/MetadataService/

with AuthUser administrator@contosoax7.onmicrosoft.com

 This settings is present in file C:\AOSService\PackagesLocalDirectory\Bin\DynamicsDevConfig.xml at the key 

<OfflineAuthenticationAdminEmail>administrator@contosoax7.onmicrosoft.com</OfflineAuthenticationAdminEmail>

 CHANGE TO BELOW

<OfflineAuthenticationAdminEmail>PUT YOUREMAIL HERE</OfflineAuthenticationAdminEmail>

We have changed this settings with AAD user, reopen VS and all works fine.

Thanks,
