Error during running with production flag on android device/ emulator

[pradipchitrakar]

I just cloned this project and tried to run the project with production flag as below:

ionic cordova run android --prod

On running the above command, I receive following error while inspecting my console using chrome://inspect/#devices.

This happens only on production build.

@pradipchitrakar Could you solve your problem? I am still struggeling of using TypeOrm for a Ionic project.

[pradipchitrakar]

@HeikoKanzler Are you getting the same problem in production? If yes, I had to change optimization to false in angular,json for production build which is not the best solution but I could not get any solution from community till now. Also, the project does not run with type orm version 0.2.25, so make sure you are using typeorm version 0.2.24 or less.

Thanks @pradipchitrakar, I just realized five minutes ago the issue with the Postgress-Driver and I am about to try it now with 0.2.24. Unfortunately, blank projects work, but adding TypeOrm to my existing project completely fails with numerous issues.
