Hi @Krishna,
Sorry for the delay in replying.
It looks like the main app (the ‘shell’) is trying to pull in the extension and compile time, which should not happen.
Were there any changes done in core/app? could you check the following file please? core/app/shell/src/app/app.module.ts
Could also check if there is any file outside the extensions folder referencing the extension.module.ts, please?
Also could you paste the following files please?
angular.jsonextensions/my-ext/app/webpack.config.jsextensions/my-ext/app/tsconfig.app.jsoncore/app/shell/webpack.config.jscore/app/shell/src/app/app.module.ts
