**重现步骤：**

1. 打开小区通讯录页面

2. 调用获取小区通讯录接口

3. 页面报错，无法正常显示通讯录数据

**预期结果：** 接口正常返回数据，页面正常显示小区通讯录 **实际结果：** 接口调用失败，报错无法读取undefined的'setChanges'属性

**错误描述：** 获取小区通讯录接口报错，无法读取undefined的'setChanges'属性。

**错误信息：** SystemError (webviewScriptError) Cannot read properties of undefined (reading 'setChanges') TypeError: Cannot read properties of undefined (reading 'setChanges') **错误堆栈：** ``` at yo (311c72c41060b088e3ccc0ca3baca051-16467-V0FXZWJ2aWV3Lmpz.cachedata:1:3111842) at 311c72c41060b088e3ccc0ca3baca051-16467-V0FXZWJ2aWV3Lmpz.cachedata:1:3110877 at 311c72c41060b088e3ccc0ca3baca051-16467-V0FXZWJ2aWV3Lmpz.cachedata:1:3110829 at Na.bo[as_startCb] (311c72c41060b088e3ccc0ca3baca051-16467-V0FXZWJ2aWV3Lmpz.cachedata:1:3110870) at Na.consumeFlow (311c72c41060b088e3ccc0ca3baca051-16467-V0FXZWJ2aWV3Lmpz.cachedata:1:3150452) at Na.flushBlocked (311c72c41060b088e3ccc0ca3baca051-16467-V0FXZWJ2aWV3Lmpz.cachedata:1:3150704) at Na.unblock (311c72c41060b088e3ccc0ca3baca051-16467-V0FXZWJ2aWV3Lmpz.cachedata:1:3150950) at Module.ts (311c72c41060b088e3ccc0ca3baca051-16467-V0FXZWJ2aWV3Lmpz.cachedata:1:3156031) at wf.dolnitRender(311c72c41060b088e3ccc0ca3baca051-16467-V0FXZWJ2aWV3Lmpz.cachedata:1:3800843) at 311c72c41060b088e3ccc0ca3baca051-16467-V0FXZWJ2aWV3LmDz.cachedata:1:3798040 ```
