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

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();
