Mashup 400 Error

[cxputcm]

HI Yannick,

Thank you for this tutorial its been easy to follow so far.

Im getting the following error when I try to make a query to graph

Details: "Microsoft.Mashup.Engine1.Library.Resources.HttpResource: Request failed: OData Version: 3 and 4, Error: The remote server returned an error: (400) Bad Request. (Object reference not set to an instance of an object.) OData Version: 4, Error: The remote server returned an error: (400) Bad Request. (Object reference not set to an instance of an object.) OData Version: 3, Error: The remote server returned an error: (400) Bad Request. (Object reference not set to an instance of an object.)"

This is some of the telemetery from the most recent error in Azure, do you have any idea what I could be doing wrong ?

Multiple things could be going wrong here, but there are some easy things to check first:

• Can you provide me with the URL you are using to call your Azure Function?
• Can you double check the following AppSettings have been configured correctly with a value?
  • KeyVaultUri
  • ClientSecretName
  • GraphBaseUrl

Hi Yannick,

Details as follows

Azure Function Call URL

https://powerbigraphprox.azurewebsites.net

I've checked for values, they seem to be there as stated in the tutorial.

I might try to rerun it, maybe I missed something.

That’s already great information, but I’d like to get the full URL with the Graph endpoint you’d like to load. Eg. https://powerbigraphprox.azurewebsites.net/V1.0/users

Hey Yannick,

Its as you've stated, is that incorrect ?

[YannickRe]

No, that url is correct.

• Did you consent to the required permissions in Azure Active Directory?
• Did you load the URL in Power BI Desktop, as an OData feed and did you select "Organizational Account" for authentication?

I just reinstalled it and tried it, worked on my end...
