我正在尝试将TradingView小部件插入到我的Next.js项目中，但是它没有显示任何内容。我在这里做错了什么吗？

import React from 'react'
import { Helmet } from "react-helmet"

function EconomicCalendar() {
  return (
    <div>
      <div className="tradingview-widget-container">
        <div className="tradingview-widget-container__widget"></div>
        <div className="tradingview-widget-copyright">
          <a href="https://www.tradingview.com/" rel="noopener nofollow" target="_blank">
            <span className="blue-text">Track all markets on TradingView</span>
          </a>
        </div>
        <Helmet>
          <script type="text/javascript" src="https://s3.tradingview.com/external-embedding/embed-widget-events.js" async>
          {`
            {
              "width": "100%",
              "height": "100%",
              "colorTheme": "dark",
              "isTransparent": false,
              "locale": "en",
              "importanceFilter": "-1,0,1",
              "currencyFilter": "AUD,USD,CAD,CNY,EUR,FRF,DEM,ITL,JPY,KRW,MYR,MXN,NZD,SGD,ZAR,ESP,CHF,TRL,GBP"
            }
          `}
          </script>
        </Helmet>
      </div>
    </div>
  )
}

export default EconomicCalendar

通常应该怎么做
