I have the same error here. It seems that ng cli, which ionic use for AoT, is not reporting errors correctly.
I tried running ./node_modules/.bin/ngc to find out the correct errors in my project. After solving all errors , ionic cordova build --prod works for me with no errors.

Adding more info about the project would be helpful.

Hello! While we appreciate you opening an issue with us I am going to close this issue and ask that you open a new one that has the issue template filled out, please.

Also providing a sample application via GitHub is always super helpful in duplicating and testing these issues.

Thanks for using Ionic!

Had the same issue, did what GuoLunHao suggested - worked a charm.

Run ./node_modules/.bin/ngc to find out the correct errors.
Solve all errors.
Try ionic cordova build --prod again

after I run ./node_modules/.bin/ngc , where do I look for the errors? My IDE is showing a bunch of new files generated, but no errors or warnings in the console
