Trying to upload files in array of objects

[sameeranand2711]

Hi,

I am trying to upload an array of objects where each object will have a list of attachments, something like:

var obj = { Description: '', RequestId: 'kjdsf9-dsfa', Items: [ { Description: '', Cost: 132.00, Files: [file1, file2]}, { Description: '', Cost: 461.25, Files: [file3, file4]} ] }

var promise = Upload.upload({ url: '/localhost/saveRequest', method: 'post', data: obj });

However, on the server, the Files array inside every object is null. Can we upload files as above? Or do we have to upload at the top level only.
