DmtsDataSource: DiscoverMonikers did not return an access token for DataSource

[SeSPowerBi]

Hello all,

Our current solution embeds Powerbi reports in the app. The reports and dashboards work but the paginated reports are creating an error. The application uses App Owns Data, Service Principal method for Power BI. The registered Power BI App is an admin of the workspace in the Power BI Service. 

I confirm that the report id given is accessible within the given workspace. Then, I provide the generateTokenRequestParameters as new GenerateTokenRequest(accessLevel: "view") since there is no RLS being applied. The tokenResponse is then generated using that generateTokenRequestParameters and the confirmed report and workspace id's. That confirmed report is then used for the embed url. The paginated report does exist and is published in the Power BI Service. 

Why is this error occurring?

@v-lionel-msft Thank you for your reply.

I have checked these resources and made sure that these steps were followed.

Our reports and dashboards are working with Power BI so I do not think that this error pertains to setup.

It is only the paginated reports that are producing this error and not embedding.
