Rdl import via API 400 Bad Request

Hi,

I have an application where you can upload .pbix and .rdl reports to PowerBI.

I can successfully import .pbix reports via API. Hovewer, when I run import for .rdl file on the API, I am getting an error - 400 Bad Request RequestedFileIsEncryptedOrCorrupted.

PowerBI setup is proper and I have a premium account, the token is proper as well.

string importURL = string.Format("{0}/groups/{1}/imports?datasetDisplayName={2}&nameConflict=Overwrite", PowerBiServiceRootUrl, GroupId, datasetDisplayName);

var importResponse = ImportPBI(FileName, importURL);


public string ImportPBI(string pbiFilePath, string url)
        {
            // create REST URL with import name in quer string
            string restUrlImportPbi = url;

            // load PBI file into StreamContent object
            var pbiBodyContent = new StreamContent(File.Open(pbiFilePath, FileMode.Open));

            // add headers for request bod content
            pbiBodyContent.Headers.Add("Content-Type", "application/octet-stream");
            pbiBodyContent.Headers.Add("Content-Disposition",
                                         @"form-data; name=""file""; filename=""" + pbiFilePath + @"""");

            // load PBI content into body using multi-part form datas
            MultipartFormDataContent requestBody = new MultipartFormDataContent(Guid.NewGuid().ToString());
            requestBody.Add(pbiBodyContent);

            // create and configure HttpClient
            HttpClient client = new HttpClient();
            client.DefaultRequestHeaders.Add("Accept", "application/json");
            client.DefaultRequestHeaders.Add("Authorization", "Bearer " + token);

            // post request
            var response = client.PostAsync(restUrlImportPbi, requestBody).Result;

            // check for success
            return response.StatusCode.ToString();

        }

Thank you and looking forward to hearing back from you.

Cheers.
