Issues with --prod flag when building my app

Ionic Framework ionic-v3

Hi there.
I’m having problems when trying to build my app with the --prod flag. I’m getting this error:

Maybe some idea about that there Ionic 3 build using "--prod" flag does not use custom webpack configuration file. Build using "--dev" flag works. · Issue #954 · ionic-team/ionic-app-scripts · GitHub and there Build Scripts error - Getting Module build failed: RangeError: Maximum call stack size exceeded when using --prod with the build · Issue #996 · ionic-team/ionic-app-scripts · GitHub

As far as I can see, the error message points me to this function on node_modules@angular\compiler\bundles\compiler.umd.js

function dedupeArray(array) {
    if (array) {
        return Array.from(new Set(array));
    }
    return [];
}

I’ve tried ionic cordova build browser --release --optimizejs --minifyjs --minifycss and it does compile (notice that I’m not including --aot)
What can I do with this??

You have extremely outdated ionic-angular and app-scripts, it could be the cause of your issues.

I haven’t tried updating ionic-angular but I’ve already tried updating app-scripts with no luck. The same error
