No files found

[amiteshCoder]

I am trying to upload a file using the chakram. But while doing so I am getting No files found error.

Here is the configuration of my test:

    const fs = require('fs');
    const chakram = require('chakram'),
    expect = chakram.expect;
    path = require("path");

   describe("Upload Image", () => {
      it("Checks endpoint for status 200", () => {

        // Arrange
        const imagesService = new ImagesService(chakram);
        let file = path.resolve('./Users/amiteshshukla/Desktop/screenshots/', 'Screen_Shot_2018-07-04 at 12.00.54.png');
        let formData = {

            "formData": {
                "file": fs.createReadStream(file),
            },
            "Content-Type": "image/png",
            "Content-Disposition": "form-data"
        };

        // Act
        const response = imagesService.hitsUploadImage(formData);
        response.then((res) => {
            console.log(res);
        });

        // Assert
        return expect(response).to.have.status(200);
    });
});

Output: body: { errors: [ 'No files found' ], response: 'failed' },

Can anyone help me in solving this . Thanks in advance
