E_UNSUPPORTED_MEDIA_TYPE The specified media type application/octet-stream is not supported

Hello,

I'm trying to pass/set custom headers for GET REST API call. On execution I'm getting below error response.


{
   "status": 415,
   "code": "E_UNSUPPORTED_MEDIA_TYPE",
   "message": "The specified media type application/octet-stream is not supported. Supported media types: [application/vnd.emc.documentum+json, application/vnd.emc.documentum+xml].",
   "details": "Content type 'application/octet-stream' not supported"
}

I would like to know whether Documentum REST API does not support the following content type - application/octet-stream

Even after specifying the following setting MediaType.APPLICATION_OCTET_STREAM_VALUE

Kindly help me in understanding the support media types.

Thanks.

In general REST resources, both XML (application/xml, application/vnd.emc.documentum+xml, application/atom+xml or application/home+xml) and JSON (application/json, application/vnd.emc.documentum+json or application/home+json) media types are supported.

Specific for Content Media Resource (i.e. /objects/{id}/content-media), the acceptable media type must be matching to the content format. For instance, a document with crtext content format accepts the media type text/plain.

You can not make application/octet-stream as a general media type to get resources.

Hi William,

Does that mean with REST we will not be able to pass/set custom parameters in the request Header?

Thanks.

You could. But Conent-Type header is not a custom header. It's the standard header for client & server to negotiate the content. You could implement a custom REST resource to accept any media types, i.e., upload specific format contents. But for the out of the box resources, you cannot customize their media types.

It might be better to answer accurately if you could tell what specific problems you want to resolve.

Thanks,

William

I was facing same issue while sending a POST request to Documentum server to create document.
{"status":415,"code":"E_UNSUPPORTED_MEDIA_TYPE","message":"The specified media type application/octet-stream is not supported.
Supported media types: [application/vnd.emc.documentum+json, application/vnd.emc.documentum+xml].",
"details":"Content type 'application/octet-stream' not supported","id":"02ddaeab-b252-4e6c-9e51-a94ed823ea06"}

After this I just removed default Content-Type from header and add "content-type":"application/vnd.emc.documentum+json"

For me issue is resolved and I am able to create document successfully.

Here is the example code:

request({
  method: 'POST',
  uri: 'http://(documentumservername)/repositories/usrel_tst/folders/(object_id)/documents',
  auth: {
        'user': 'username',
        'pass': 'password',
        'sendImmediately': false
        },
  headers: {
          "content-type": "application/vnd.emc.documentum+json",
          "format":"pdf"
      },
  body: JSON.stringify(
        {"properties":
             {"object_name":"Test Doc 3.pdf",
             "r_object_type":"dm_document",
             "a_content_type":"pdf"}})

  },
function (error, response, body) {
  if (error) {
    return console.error('upload failed:', error);
  }
  console.log('Response Body:', body);
})
