[图片][图片] 近期，小程序两次发版之后，we分析后台冷启动耗时数据抖动异常。 由上图，可以看出，该数据抖动与资源准备阶段耗时抖动相关。 [图片] [图片] 由上图代码包下载耗时及小程序的启动流程，可以看出，资源准备阶段，代码包下载耗时数据为正常波动，无异常抖动。 烦请官方协助排查一下，微信侧最近有无相关调整或者其他原因，导致小程序发版，启动耗时异常抖动。

安卓、skyline引擎，0828开始出现大量错误 现象：1、安卓手机，微信8.0.51版本，使用普通二维码调起小程序进入指定页面，调用wx.requestPayment无回调，并报下面错误 通过小程序码/链接进入可以正常收到wx.requestPayment回调，该页面切换为webview渲染，可以正常收到回调 2、ios手机，8.0.53版本，普通二维码调起或者小程序码调起，均可以正常收到wx.requestPayment回调，skyline和webview均无问题 [system] Error: nextMicroTaskCallback occur fatal error:  {type: "string", description: "[system] Error: nextMicroTaskCallback occur fatal error: ", value: "[system] Error: nextMicroTaskCallback occur fatal error: "} TypeError: Cannot read properties of undefined (reading 'replace') {type: "object", description: "TypeError: Cannot read properties of undefined (reading 'replace')", objectId: "15", className: "TypeError", subtype: "error", preview: {type: "object", description: "TypeError: Cannot read properties of undefined (reading 'replace')", properties: [], overflow: true, subtype: "error"} (in promise) SystemError (appSubContextSDKScriptError) Cannot read properties of undefined (reading 'replace') TypeError: Cannot read properties of undefined (reading 'replace') at (WAServiceMainContext.js:1:2007355) at (WAServiceMainContext.js:1:792535) at Object.cb (WAServiceMainContext.js:1:659611) at H._privEmit (WAServiceMainContext.js:1:104726) at H.emit (WAServiceMainContext.js:1:105016) at Object.cb (WAServiceMainContext.js:1:659721) at H._privEmit (WAServiceMainContext.js:1:104726) at H.emit (WAServiceMainContext.js:1:105016) at T.__onMsgCallback (WAServiceMainContext.js:1:2436057) at T.__onMessageHandler (WAServiceMainContext.js:1:2409965) {type: "string", description: "(in promise) SystemError (appSubContextSDKScriptError)\nCannot read properties of undefined (reading 'replace')\nTypeError: Cannot read properties of undefined (reading 'replace')\nat (WAServiceMainContext.js:1:2007355)\nat (WAServiceMainContext.js:1:792535)\nat Object.cb (WAServiceMainContext.js:1:659611)\nat H._privEmit (WAServiceMainContext.js:1:104726)\nat H.emit (WAServiceMainContext.js:1:105016)\nat Object.cb (WAServiceMainContext.js:1:659721)\nat H._privEmit (WAServiceMainContext.js:1:104726)\nat H.emit (WAServiceMainContext.js:1:105016)\nat T.__onMsgCallback (WAServiceMainContext.js:1:2436057)\nat T.__onMessageHandler (WAServiceMainContext.js:1:2409965)", value: "(in promise) SystemError (appSubContextSDKScriptError)\nCannot read properties of undefined (reading 'replace')\nTypeError: Cannot read properties of undefined (reading 'replace')\nat (WAServiceMainContext.js:1:2007355)\nat (WAServiceMainContext.js:1:792535)\nat Object.cb (WAServiceMainContext.js:1:659611)\nat H._privEmit (WAServiceMainContext.js:1:104726)\nat H.emit (WAServiceMainContext.js:1:105016)\nat Object.cb (WAServiceMainContext.js:1:659721)\nat H._privEmit (WAServiceMainContext.js:1:104726)\nat H.emit (WAServiceMainContext.js:1:105016)\nat T.__onMsgCallback (WAServiceMainContext.js:1:2436057)\nat T.__onMessageHandler (WAServiceMainContext.js:1:2409965)"}
