if the proxyRes with bad statusCode, how can i retry the proxyRequest.

I want to automatically bring the token when the statusCode is 401 and re-request。 for example：

onResponseInterceptor: (proxyRes, req, res, retry) => {
        if (proxyRes.statusCode == 401) {
            retry()
        }
}

and the retry function is defined by:

  this.proxy.on("proxyRes", (proxyRes, req, res) => {
      console.log(req.headers);
      const retry = async () => {
          await this.option.beforeRetry?.(proxyRes, req, res)
          const retry = (req.headers['x-retry'] || '0') as string;
          req.headers["x-retry"] = (Number(retry) + 1).toString()
          this.proxy.web(req, res,{
              target: this.option.target,
              changeOrigin: true,
              selfHandleResponse: true
          })
      }
      this.option.onResponseInterceptor?.(proxyRes, req, res, retry)
  })

I tried to re-launch proxy.web() in proxy.on("proxyRes"). But this doesn't work and no second response is received. How do I solve this problem?
