【报Bug】支付宝小程序使用 life-follow 组件，调用 oncheckFollow 函数报错

示例代码：

<!--  #ifdef MP-ALIPAY  -->    
            <life-follow :sceneId="'2e73934c888345aab97a3bdbef18cae6'" v-if="showFollow" :checkFollow="isFollow"   
                @checkFollow="checkFollowFunc($event)" @close="closeFunc($event)" />  
            <!--  #endif -->  

checkFollowFunc(event){  
        console.log(event, "::checkFollow::")   
        if(event && event.detail){  
            const { followed, closeCount } = event.detail || {}  
            this.isFollow = false  
            this.showFollow = false  
            /**如果没有关注的话，展示组件 */  
            if(!followed){  
                this.$nextTick(() => {  
                    this.showFollow = true  
                    this.show = true  
                })  
            } else {  
                this.$nextTick(() => {  
                    this.showFollow = false  
                    this.show = false  
                })  
            }  
        }  
    }

操作步骤：

<!--  #ifdef MP-ALIPAY  -->    
            <life-follow :sceneId="'2e73934c888345aab97a3bdbef18cae6'" v-if="showFollow" :checkFollow="isFollow"   
                @checkFollow="checkFollowFunc($event)" @close="closeFunc($event)" />  
            <!--  #endif -->  

checkFollowFunc(event){  
        console.log(event, "::checkFollow::")   
        if(event && event.detail){  
            const { followed, closeCount } = event.detail || {}  
            this.isFollow = false  
            this.showFollow = false  
            /**如果没有关注的话，展示组件 */  
            if(!followed){  
                this.$nextTick(() => {  
                    this.showFollow = true  
                    this.show = true  
                })  
            } else {  
                this.$nextTick(() => {  
                    this.showFollow = false  
                    this.show = false  
                })  
            }  
        }  
    }

预期结果：

能正常获取到 oncheckFollow 返回的值

实际结果：

控制显示报错
