This seems to be an issue with the dependencies in the project package.json file. Could you verify whether all of them are up to date while following the below-attached sample:
{
"description": "NativeScript Application",
"license": "SEE LICENSE IN <your-license-filename>",
"readme": "NativeScript Application",
"repository": "<fill-your-repository-here>",
"nativescript": {
"id": "org.nativescript.testNG"
},
"dependencies": {
"#angular/animations": "~4.4.1",
"#angular/common": "~4.4.1",

"reflect-metadata": "~0.1.8",
"rxjs": "~5.4.2",
"tns-core-modules": "~3.2.0",
"zone.js": "~0.8.2"
},
"devDependencies": {
"#angular/compiler-cli": "~4.4.1",

"nativescript-dev-webpack": "^0.8.0",
"nativescript-worker-loader": "~0.8.1",

"typescript": "~2.4.2",

},
"scripts": {
"ns-bundle": "ns-bundle",
"start-android-bundle": "npm run ns-bundle --android --run-app",
"start-ios-bundle": "npm run ns-bundle --ios --run-app",
"build-android-bundle": "npm run ns-bundle --android --build-app",
"build-ios-bundle": "npm run ns-bundle --ios --build-app",
"publish-ios-bundle": "npm run ns-bundle --ios --publish-app",
"generate-android-snapshot": "generate-android-snapshot --targetArchs arm,arm64,ia32 --install"
}
}
After that delete node_modules and platforms folders. Run npm install and try to rebuild the project with npm run build-android-bundle --uglify
If the problem still persists, please provide some more info about the issue and share your package.json file. It would help if you could provide some sample project, which could be debugged locally.
