Syntax to POST a MEDIA from Zoho CRM to Wordpress Media Libray (Zoho Deluge)

Hi,

I try to post a picture from a product from Zoho CRM to Worpdress Media Library.

This is what i'm doing but i have an error : Execution exception : 'Error due to - 'Internal Exception'' 

  1. picture= ifnull(prodDetails.get("picture"),"");

  3. map = Map();
  4. map.put("title",title);
  5. map.put("alt_text",title);

  7. response = invokeUrl [
  8.       url : "https://mywordpress.com/wp-json/wp/v2/media"
  9.       type : POST
  10.       files : picture
  11.       parameters : map
  12.       connection : "my_connection"
  13. ];

I know that my connection is ok because i'm able to POST some wordpress post with it.

Any idea  ?
Thanks ?
