I had a problem using Power BI Embedded "AppOwnsData" sample. I setup an application account and ran the sample and the report wouldn't load, saying "This content isn't available." I couldn't find any answers online other than "your token is bad." I took the token from the executing code in the debugger and tried using it in the Embedded Playground, which gave me the error message "To view this report, ask the author for access". Then I did the reverse and got a valid token from the API sample (using my own logon which I had working before I started using the application account) and stuffed it into the code in the debugger and that worked. This told me that the code was indeed getting a bad token using the application account. The API doc says the app account only needs these permissions:
- Report.ReadWrite.All or Report.Read.All
- Dataset.ReadWrite.All or Dataset.Read.All
My dataset uses a Gateway, and it appears that Gateway.Read.All permission is also needed on the app account. Because the error messages were so vague and I couldn't find any help, I thought it might be a good idea to post it here for the next person stuck.
Microsoft, is there a way to update the API doc to show this permission is required for datasets using a Gateway? Extra points if the error message could be improved! The second error message was pointing at a report access issue, when the root cause was a Gateway permission.
