the request was rejected because no multipart boundary was found when creating new document in Docushare Flex

Question

I am trying to create new document in Docushare Flex using new docushare rest api and my request body suppose to be XML and I am generating it with requested data, when I send the request I get this error "org.apache.commons.fileupload.FileUploadException: the request was rejected because no multipart boundary was found"

    HttpPost request = new HttpPost(postUrl);
    String filePath = "C:/Test/CreateDocument.xml";
    String createObj =  helper.createDocumentXml(filePath, parentId, documentTitle, fileName, ownerId);
    String createDocumentXml= null;
    {
        try {
            createDocumentXml = FileUtils.readFileToString(new File(filePath));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    StringEntity bodyEntity = new StringEntity(createDocumentXml, ContentType.MULTIPART_FORM_DATA);
    request.setEntity(bodyEntity);

    CloseableHttpResponse response =  client.execute(request);
    System.out.println("Status is " +  response.getStatusLine());
    HttpEntity entity = response.getEntity();

I have used this block of code to upload a document in DocuShare Flex

HttpPost request = new HttpPost(postUrl);
String filePath = "C:/Test/CreateDocument.xml";
String createObj =  helper.createDocumentXml();
String createDocumentXml= null;
{
    try {
        createDocumentXml = FileUtils.readFileToString(new File(filePath));
    } catch (IOException e) {
        e.printStackTrace();
    }
}
    FileBody body = new FileBody(file.toFile());

    StringBody xmlContent = new StringBody(createDocumentXml, ContentType.APPLICATION_XML);
    String boundry = UUID.nameUUIDFromBytes(file.toString().getBytes()).toString();
    HttpEntity entity = MultipartEntityBuilder.create()
            .setBoundary(boundry)
            .setCharset(Charset.forName("UTF-8"))
            .setMode(HttpMultipartMode.BROWSER_COMPATIBLE)`enter code here`
            .addPart("content", body)
            .addPart("request", xmlContent)
            .build();

    request.setEntity(entity);

    CloseableHttpResponse response =  client.execute(request);
    HttpEntity entity = response.getEntity();
