调用米大师支付接口报错 ：errMsg: "requestMidasPayment:fail 请求参数错误(pfkey)", errCode: 1001

文档中没有对应解释，希望能解释下什么问题

示例代码：

wx.requestMidasPayment({

mode: "game",

env: 1,

offerId: "xxxxxx",

currencyType: "CNY",

platform: "android",

buyQuantity: data.amount * 10,

zoneId: "1",

success(res) {

},

fail(res) {

},

complete(res) {

}

})
