Hello all,
My local solution is a Power BI ASP.NET web app registered in Azure AD using a client secret and client id (Azure service principal with a App Owns Data model). It preforms the Power BI REST API call "export=client.Reports.ExportToFileInGroup(workspaceid, reportid, exportRequest)" but it is catching a 400 Bad Request error.
When I tried testing https://docs.microsoft.com/en-us/rest/api/power-bi/reports/exporttofileingroup TryIt workspace it executed the request with a 200 response using the same groupid and reportid in our Azure account.
When I tried testing https://api.powerbi.com/v1.0/myorg/groups/:groupid/reports/:reportid/ExportTo from Postman with the Bearer token retrieved from https://login.microsoftonline.com/:tenant/oauth2/token for our Registered App (used in the local solution) within that Azure workspace, the error remains the same --Bad Request.
I have my header set to "Authorization: Bearer #######" and "Content-Type: application/json" to match TryIt, with the body set as "{"format": "PDF"}".
When I have taken the Bearer token from the TryIt workspace, and used it in the Postman call, the error persists.
Why is this error persisting? Has anyone delt with this call before and recieved a similar issue?

Hi @v-yiruan-msft,
I had to use Fiddler to get more information on the error. It has to do with effective identities that needed to be provided in the body for RLS.
The links were helpful when determing the body for the request in Postman for RLS, however more research was required for how to apply it in our ASP.NET web app.
This has been resolved now, thank you for your help.
