Sentry with sourcemap issue hence it is not showing ts details

I use Sentry with Ionic 3 app. I use Sentry Cordova plugin and all are working fine on Sentry dashboard. But one thing is missing. i.e. it doesn’t show .ts files. It seems to be a sourcemap issue. Any clues on how to solve this issue?

Below are the screenshots with missing ts details and package.json and dependencies:

tsconfig.json
