question: Class Validator throws ',' expected when I run "tsc"

See original GitHub issue

Description

I’m using TypeORM and Class Validator together. I need to deploy my app to heroku now, so I created a script called “npm build”, which runs the command “tsc”. However, it shows these errors which made my app unable to deploy. Below are the errors:

Found 8 errors.

Expected behavior

I’ve tried uninstalling and reinstalling class validator, but in vain. I expect it to have zero errors and my app successfully deployed to heroku.

Actual behavior

What happens is that the errors above are thrown, making me unable to deploy my application.
