Files can be a maximum size of 250 mb. Currently only supports local storage. A valid URL (e.g. https://www.abc.com/myfile.jpg, not wwww.abc.com/myfile.jpg) can be given as a optional parameter which will be used to fetch a file from the URL provided instead of uploading a file directly from local machine. Note that Swagger cannot be used for testing file uploads, please use another external tool (e.g. Postman).
