I am having problem with the alertController because it in the --prod option does not work the alert buttons. Does anyone else have this problem?

Probably unrelated, but it looks as though you haven’t updated your Node in over a year. Lots of security vulnerabilities. Best to update to the current LTS.

Ok! I go see it´s “Node”

I still have the same problem even updating node js

What does your alert controller code look like?
