Issue in the dropzone.min.js file in Celebrity Face Recognition project

[kanakmi]

If we run the file on the system, there is no issue but when we deploy it on Heroku and try to remove the image after uploading, an error popup is shown.

I have actually resolved this issue, please assign it to me so that I can change it here as well.
