04-27 11:06:47.507 31991 32031 I ReactNativeJS: 'error signing up: ', 'JSON Parse error: Unrecognized token \'?\''

让我感到困惑的是错误：'JSON Parse error: Unrecognized token \'?\'。
这是应用程序中的获取：

let obj = JSON.stringify({
            _device_id: DeviceInfo.getUniqueID(),
            cell: cell,
            cell_country_code: cell_country_code,
            name: username,
            corp_name: corp_name,
          });
          console.log("obj : ", obj);
          let res = await fetch(url, {
            method: "POST",
            headers: {
              'Accept': 'application/json',
              'Content-Type': 'application/json',   
            },
              body: obj,
            });

此响应来自Nodejs 10.15服务器，返回的数据主体为空。仅设置了标题。

res.set("x-auth-token", "ok to proceed");
return res.status(200).send('Vcode sent out successfully');

我应该从'Accept' : 'application/json'中删除fetch body吗？ JSON.parser来自何处以及导致错误的原因？

响应具有JSON解析错误：无法识别的令牌\'？\'
