Error while importing .pbix using powerbi-client

If you're using the NodeJS Power BI SDK, it is no longer supported. Try to directly call the REST API instead.

I don't know NodeJS, you can reference how I call the Create Import REST API in C#.

 static void Main(string[] args)
        {
            //Import sample 
            string pbixPath = @"C:\test\2.pbix";
            string datasetDisplayName = "mydataset";

            string importResponse = Import(string.Format("{0}/groups/{1}/imports?datasetDisplayName={2}", datasetsBetaUri, groupId, datasetDisplayName), pbixPath,"Bearer Token here");
              
            Console.WriteLine(importResponse);

        }

        public static string Import(string url, string fileName,string bearerToken)
        {
            string responseStatusCode = string.Empty;

            string boundary = "---------------------------" + DateTime.Now.Ticks.ToString("x");
            byte[] boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "\r\n");

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

            request.ContentType = "multipart/form-data; boundary=" + boundary;
            request.Method = "POST";
            request.KeepAlive = true;
            request.Headers.Add("Authorization", String.Format("Bearer {0}", bearerToken));

            using (Stream rs = request.GetRequestStream())
            {
                rs.Write(boundarybytes, 0, boundarybytes.Length);

                string headerTemplate = "Content-Disposition: form-data; filename=\"{0}\"\r\nContent-Type: application / octet - stream\r\n\r\n";
                string header = string.Format(headerTemplate, fileName);
                byte[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header);
                rs.Write(headerbytes, 0, headerbytes.Length);

                using (FileStream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read))
                {
                    byte[] buffer = new byte[4096];
                    int bytesRead = 0;
                    while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
                    {
                        rs.Write(buffer, 0, bytesRead);
                    }
                }

                byte[] trailer = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "--\r\n");
                rs.Write(trailer, 0, trailer.Length);
            }
            using (HttpWebResponse response = request.GetResponse() as System.Net.HttpWebResponse)
            {
                responseStatusCode = response.StatusCode.ToString();
            }
                         return responseStatusCode;
        }
