I am trying to send the multipart/formdata request to external system. While invoking the endpoint, I'm facing this data handler issue. I'm Getting some conflicts within data handler.
InputStream inputStream = new ByteArrayInputStream(byte[] dummy);
ContentDisposition cd = new ContentDisposition("attachment;filename=image.jpg");
Attachment attachment = new Attachment("root", imageInputStream, cd);
response = myDummyProxy.externalAPICall(attachment,myMetadata);
I am sending this request containing attachment and metadata after which getting this Data Handler Incompatible exception.
