resact pdf,`Save in File`函数引发异常

当按钮点击时。调用render并抛出异常pic,如下所示;

预期行为:下载文件名“example.pdf”

import ReactPDF from "@react-pdf/renderer";

    const GenerateBarcode = () => {
        ReactPDF.render(<p>Some Jsx Elements</p>, `${__dirname}/example.pdf`);
      };
    
      return (
        <div>
          <button
                                      className="btn btn-primary "
                                      type="button"
                                      onClick={GenerateBarcode}
                                    >
                                     Generator PDF
                                    </button>
