Microsoft.PowerBI.API issues - PowerBIReportExportConfiguration - MethodNotAllowed

Good morning all,

     On Wednesday, 5/4, our API report generator started returning Microsoft.Rest.HttpOperationException: Operation returned an invalid status code 'MethodNotAllowed' when we are requesting an ExportID.  The script that we are using below is what is running.

private static async Task<string> PostPowerBIExportRequest(Guid groupId, Guid reportId, PowerBIClient client)
        {
            Console.WriteLine("The PowerBI Export Request has fired.");

            var powerBIReportExportConfiguration = new PowerBIReportExportConfiguration
            {
                Settings = new ExportReportSettings
                {
                    Locale = "en-us",
                },

            };
            var exportRequest = new ExportReportRequest
            {
                Format = FileFormat.PDF,
                PowerBIReportConfiguration = powerBIReportExportConfiguration,
            };

            try
            {
                var export = await client.Reports.ExportToFileInGroupAsync(groupId, reportId, exportRequest);

                return export.Id;
            }
            catch (Exception e)
            {
                Console.WriteLine("PowerBIExportConfiguration step has failed.");
                Console.WriteLine(e.ToString());
                return "Failure";
            }
        }

Please let me know what steps to take to remedy this outage.

Thank you,

J.R.
