HarmonyOS 鸿蒙Next开启混淆后报错Cannot read property includes of undefined

HarmonyOS 鸿蒙Next开启混淆后报错Cannot read property includes of undefined 在依次开启下面三项混淆规则后，项目报错：

-enable-toplevel-obfuscation
-enable-property-obfuscation
-enable-export-obfuscation
  1. 报错的详细信息如下：
VersionCode:7052
PreInstalled:No
Foreground:Yes
Pid:50927
Uid:20020005
Reason:TypeError
Error name:TypeError
Error message:Cannot read property includes of undefined
Stacktrace:
Cannot get SourceMap info, dump raw stack:
    at anonymous (entry|entry|1.0.0|src/main/ets/pages/main/MainPage.ts:771:1)
  1. 混淆前的代码如下：
Image(tabBarModel.icon.includes("http") ? tabBarModel.icon : $r(tabBarModel.icon))
    .width(24)
    .height(24)
    .objectFit(ImageFit.Contain)
    .visibility(this.currentTabBarModel?.tabType === tabBarModel.tabType ? Visibility.Hidden :
    Visibility.Visible)
  1. 混淆后的代码如下：
this.observeComponentCreation2((elmtId, isInitialRender) => {
    Image.create(o135.icon.includes("http") ? o135.icon : { "id": -1, "type": -1, params: [o135.icon], "bundleName": "com.com.ccmm", "moduleName": "entry" });
    Image.debugLine("entry/src/main/ets/pages/main/MainPage.ets(381:11)", "entry");
    Image.width(24);
    Image.height(24);
    Image.objectFit(ImageFit.Contain);
    Image.visibility(this.currentTabBarModel?.tabType === o135.tabType ? Visibility.Hidden :
        Visibility.Visible);
}, Image);

报错信息显示是调用了includes方法后导致了崩溃，即调用了tabBarModel.icon.includes("http")这段代码后出问题。而tabBarModel是一个传入进来的class对象，icon是其一个string类型的属性。为什么这里会出现includes的错误呢？我该怎么去keep？

在HarmonyOS鸿蒙Next中开启混淆后出现“Cannot read property ‘includes’ of undefined”错误，通常是由于混淆工具在处理代码时，未能正确识别或保留某些关键属性或方法。includes是JavaScript中数组的原生方法，混淆过程中可能被误删或替换，导致运行时无法找到该方法。

解决方法可以尝试在混淆配置文件中明确排除includes方法或相关代码段，确保其在混淆过程中不被修改。具体操作可以在proguard-rules.pro文件中添加排除规则，如：

-keep class * {
    public *;
    -keepclassmembers class * {
        public *;
    }
}

或针对includes方法的排除：

-keepclassmembers class * {
    boolean includes(java.lang.Object);
}

确保混淆配置正确后重新编译项目，错误应可解决。
