unipay 2.0 查询订单以及退款问题

最近在使用unipay 2.0的时候，发现两个问题：
1.查询订单状态，订单实际是由于支付金额不足，支付失败的。
调用一下代码，参数均正确：
let res = await this.$refs.pay.getOrder({
out_trade_no: outTradeNo, // 插件支付单号 两者传1个即可
await_notify: true
});
然后，就会弹出提示弹窗，Cannot read properties of undefined (reading 'total')。
云函数报错：
11:12:56.815 [本地调试]TypeError: Cannot read properties of undefined (reading 'total')

11:12:56.815 [本地调试] at async ce.getOrder (H:\uni_modules\uni-pay\uniCloud\cloudfunctions\uni-pay-co\index.obj.js:152:9)

而且没有办法用 try catch将错误自己处理掉。大概率是因为会弹出提示弹窗的原因。

2.使用订单退款，报错。
调用函数，参数正确，也正常退款，但是，报错是修改数据库的错误。
let res = await this.$refs.pay.refund({
out_trade_no: outTradeNo, // 插件支付单号
});
11:14:38.592 [本地调试]FaasError: code: 100104, error: (BadValue) The argument to $each in $push must be an array but it was of type: object uni_modules/uni-pay/uniCloud/cloudfunctions/uni-pay-co/service/pay.js:659:12

更新到最新的unipay 2.2.1版本也报错。请求大神解答！
