    generateUniqueIdentifier: ((file: File, event: Event) => {
        var relativePath = file.webkitRelativePath||file.fileName||file.name; // Some confusion in different versions of Firefox
        var size = file.size;
        return(size + '-' + relativePath.replace(/[^0-9a-zA-Z_-]/img, ''));
      }) as () => string,
...

Returns:

Type '(file: File, event: Event) => string' is not assignable to type '() => string'.ts(2322)

This happens because:

  generateUniqueIdentifier?: () => string;

Also, File type won't handle the attributes webkitRelativePath file.relativePath or file.fileName
