Hi All,

We are trying to make a ajax POST call to /documents/api/1.2/files/data rest end point.

Here what should be the input for the primaryFile parameter.

  Tried setting the primaryFile to File, Blob but nothing worked.

  var file = new File([image], 'myImage', {type: image/png}); // Here image is the response from a GET call whose return type is a arraybuffer. Tried blob as well.

   The same call via servlet works fine but via ajax call in my javascript it fails.
