IOS内发起iap支付后app直接卡死是什么原因？

如题，以下是代码，console.log(productSuccess)能正常输出产品信息，但是无法进入uni.requestPayment，APP直接卡死：

uni.getProvider({  
                  service: 'payment',  
                  success: async (paymentRes) => {  
                    const iapChannel = paymentRes.providers.find((channel) => {  
                      return (channel.id === 'appleiap')  
                    })  
                        iapChannel.requestProduct(['com.xd.open.vip','com.xd.renew.vip'],function(productSuccess){  
                            console.log(productSuccess)  
                            uni.requestPayment({  
                                provider:'appleiap',  
                                orderInfo: {  
                                    productid: 'com.xd.open.vip',  
                                    username: res.id,  
                                    quantity: 1,    
                                    manualFinishTransaction: true  
                                },  
                                success: (paySuccess) => {  
                                    console.log(paySuccess)  
                                },  
                                fail: (payFail) => {  
                                    console.log(payFail)  
                                }  
                            })  
                        },function(productFail){  
                            console.log(productFail)  
                        })  
                  }  
                });
