File uploads using multipart/form-data not working

Adding this to my js file

let multipartHeaders = [
  {
    "name": "content-type",
    "value": "multipart/form-data"
  },
  {
    "name": "example-oauth-v1",
    "value": "<oauth_access_token>"
  }
];

let snippets = {
    usecasesUploadFile: new HTTPSnippet({
      method: 'POST',
      url: "https://www.example.com/api/projects/0.1/projects/15339651/files/",
      headers: multipartHeaders,
      postData: {
        mimeType: "multipart/form-data",
        params: [
          {
            name: "filedata",
            fileName: "/project_dir/sample_file.txt",
            contentType: "text/plain"
          }
        ]
      }
    }),
}

Returns this:

TypeError: form.pipe is not a function
HTTPSnippet../node_modules/httpsnippet/src/index.js.HTTPSnippet.prepare
node_modules/httpsnippet/src/index.js:118

 115 |   })
  116 | })
  117 | 
> 118 | form.pipe(es.map(function (data, cb) {
  119 |   request.postData.text += data
  120 | }))
  121 |

Is there something wrong with my usage?

A fix for this is in https://github.com/Kong/httpsnippet/pull/173!
