PC开发环境操作系统： Windows
PC开发环境操作系统版本号： win10
HBuilderX类型： 正式
HBuilderX版本号： 3.98
手机系统： Android
手机系统版本号： Android 9.0
手机厂商： 模拟器
手机机型： 雷电模拟器
页面类型： vue
vue版本： vue3
打包方式： 离线
项目创建方式： HBuilderX
示例代码：
操作步骤：
第一步：使用hbuilder 基于uniapp默认模板创建项目
第二步：编写网页，引入uni-webview.js，监听UniAppJSBridgeReady，然后uni.postMessage
第三步：编写代码plus.webview.create，加载那个网页，postMessage触发后就触发了以上描述的报错
第一步：使用hbuilder 基于uniapp默认模板创建项目
第二步：编写网页，引入uni-webview.js，监听UniAppJSBridgeReady，然后uni.postMessage
第三步：编写代码plus.webview.create，加载那个网页，postMessage触发后就触发了以上描述的报错
预期结果：
uni.postMessage不要触发报错，报错之后app无法交互
uni.postMessage不要触发报错，报错之后app无法交互
实际结果：
uni.postMessage会触发报错，报错之后app无法交互
uni.postMessage会触发报错，报错之后app无法交互
bug描述：
plus.webview.create创建网页后，网页中uni.postMessage会触发报错
