Odata Connection Refresh Error while using excel web app - Project Online 2013

Hello All,

I am trying to work with odata reporting on project online 2013. I am not using MS Excel client, I open any of the available default report in excel online. when i try to refresh data connection from data tab. it's giving me an error as show below 
screen..


I have already enabled "PWA for excel web app refresh" feature.  

Following the blog instructions and microsoft support, i have tried to grant permission to

AppId=  00000009-0000-0000-c000-000000000000

And In the Permission Request XML field, copy and paste the following XML: 

<AppPermissionRequests>

    <AppPermissionRequest Scope = "http://sharepoint/projectserver/reporting" Right="Read">

    </AppPermissionRequest>

    <AppPermissionRequest Scope = "http://sharepoint/content/tenant" Right="FullControl">

    </AppPermissionRequest>

</AppPermissionRequests>

Now, According to the microsoft, it should show Microsoft.Azure.Azureservices as Title but as per below screen shot it shows Power BI Reporting and Analytics.. title.<o:p></o:p>

However, i click on ok button and check that the permission has been granted. i can see Microsoft Power BI reporting and analytics in the app permissions.

I again go to my BI reporting, open my report in excel online and refresh the data connection and nothing changed. It's giving me the same error.

I hope that i am able to narrate my problem. Please tell me, What i am missing here...
