I am trying to build release APK but getting the following error:

[11:31:46] copy started …
[11:31:46] deeplinks started …
[11:31:47] deeplinks finished in 481 ms
[11:31:47] ngc started …
[11:31:49] ionic-app-script task: “build”
[11:31:49] TypeError: Object prototype may only be an Object or null: undefined

I had the same problem. You need run: Ionic cordova build android –release. That is, without flag --prod.

Hi,

consider this a workaround…not a solution as there is still an issue in your code…

ionic build --aot to continue the debugging without the lengthy cordova tail part…

ionic build --aot is also giving same error.

I have tried with Ionic cordova build android –release and done the job but apk is not optimized.
