Powerbi exportTo api bookmark state error

[Anonymous]

Hi everyone,

I have embded power-bi report into react App using service priciple and I'm using exportTo post api to get report in ppt/pdf format.

let result = await fetch(

      `https://api.powerbi.com/v1.0/myorg/groups/${data.workSpaceId}/reports/${data.reportId.id}/ExportTo`,

      {

        method: "POST",

        headers: headers,

        body: JSON.stringify(formData),

      }

    );

formData = {

      format: "PPTX",

      powerBIReportConfiguration: {},

    };

    formData.powerBIReportConfiguration["identities"] = [

      {

        username: data.user.email,

        roles: ["RLS"],

        datasets: ["xyz"],

      },

    ];

    formData.powerBIReportConfiguration["pages"] = [{ pageName: data.page }];

    formData.powerBIReportConfiguration["defaultBookmark"] =

      data.bookMark.body.state;

I have used report.bookmark.Capture() and report.bookmarksManager.applyState() to apply and get bookmark state of app based on user interaction.But as I add bookmark state property in FormData I get

HI @Anonymous,

As the document said, the bookmark parameter seems allow two methods, name and state. If state not work on your scenario, Have you try to change to use the bookmark name?
