I am trying to download JSON data ( response object ) as a json file but when I tried to achive this using browser File() object , it gives error

Failed to construct 'File': Iterator getter is not callable.

below is my code

//`inputData` is the valid response getting from $http.get
var stringifyData = JSON.stringify(inputData);
console.log("stringifyData ", stringifyData);
var file = new File(blob, "filename.json", {type: "text/json;charset=utf-8"});
console.log("file", file);

what is the issue and why I am getting this error. when I use JSON.stringify(inputData, undefined, 4); then it gives no error and displays proper object in the console.

I know I am late but I am facing the same issue so I thought should post my function it will help to convert BLOB to FILE. Thanks 

 imageCropped(event: ImageCroppedEvent) {
    this.Files = event.file;
    let fileName = new Date().getTime() + ".jpeg";
    let filedata = new File([this.Files], fileName, {
      type: "image/jpeg",
      lastModified: Date.now()
    });
    console.log(filedata);
  }
