Power BI Embedded authentication error

E-Mac2 — Tue, 20 Jun 2017 16:25:54 GMT

Hi all,

I have been trying to run the samples from the following link: https://powerbi.microsoft.com/en-us/documentation/powerbi-developer-integrate-dashboard/

I followed the steps, but I get an authentication error in both the 'App owns data' and 'User owns data' samples.

In the 'App owns data' sample I get the following error :

Operation returned an invalid status code 'Forbidden'

on the following line of code:

var tokenResponse = await client.Reports.GenerateTokenInGroupAsync(GroupId, report.Id, generateTokenRequestParameters);

In the 'User owns data' dashboard sample, I get the following error:

As I clicked 'Sign in to Power BI' and entered details I received an authentication error 'System.FormatException: 'Index (zero based) must be greater than or equal to zero and less than the size of the argument list.' at AuthenticationResult AR = AC.AcquireTokenByAuthorizationCode(code, new Uri(redirectUri), cc); in redirect.aspx.cs

Any help on these would be great, thanks.

@E-Mac2

Please try to follow below steps.

1. Register a new Azure AD app.

2. Go to Azure portal, login with the User used when registering the app. Then find the registered Azure app.

3.Then edit required permisson, select all checkboxes for Power BI Services and click Save. At last, click Grant Permission and click yes.

Hi @Eric_Zhang

Thanks for the reply.

I mananged to solve the first problem. I was trying to access a private group using it's ID. I created a new 'open' group. This allowed me to access the report using the group ID.

As for the second issue, I tried the above permission changes but the problem still persists 😕

Were you able to resolve the issue with returning a "Forbidden"? I am working through testing a solution and am now receiving the same error.

Whenever the code executes the following line:

var tokenResponse = await client.Reports.GenerateTokenInGroupAsync(GroupId, report.Id, generateTokenRequestParameters);

This sample was working with no issues yesterday but this morning now it is returning this error.

Hi @Anonymous

Were any of the security settings of the group changed recently?

The way I worked around it was by creating a new non-private group and replacing the group ID in the code with the new group ID from the newly created group.

Hmm.

I added members to the group but that's all that has changed. Randomly it started working for a few minutes but now it's returning a forbidden error again. It seems to me that something is going on with the service that's causing an issue. I could make the group public but that isn't ideal for security reasons.
