sendSocketMessage下图手机上函数没有执行，请问下原因

报错如下

wx.sendSocketMessage的值 function (){try{return e.apply(e,arguments)}catch(e){if("[object Error]"===Object.prototype.toString.apply(e)){if("AppServiceSdkKnownError"==e.type)throw e;Reporter.errorReport({key:"appServiceSDKScriptError",error:e,extend:t})}}}

第二个框

在手机上，这个函数没有执行

我一个手机调试模式出的信息是 wx.sendSocketMessage的值 和电脑上一样，一个手机出的信息是null

appservice这样写的

//跳转聊天室   chatRoom:function(e){     var userid=e.currentTarget.dataset.userid;     var name=e.currentTarget.dataset.name;     var avatar=e.currentTarget.dataset.avatar;     wx.navigateTo({       url: '../chatRoom/chatRoom?u=' + userid + '&n=' + encodeURIComponent(name) + '&a=' + avatar     });   },   }) function sendSocketMessage(msg) {   if (socketOpen) {     console.log('wx.sendSocketMessage的类型 '+ typeof wx.sendSocketMessage)     console.log('wx.sendSocketMessage的值 '+ wx.sendSocketMessage)     wx.sendSocketMessage({       data:msg,       success:function(data){         //console.log(data);       }     })   } else {      console.log("请先建立连接")   } }
