FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

Error when running command: ionic cordova build android --prod

Note: that ionic build android, ionic run android and ionic serve all works fine.

I've read many topics that says once the project gets bigger, it stops working.

It was working the day before issue arrive. It stopped working as we added more files and JSON for translation of app in multi-language.

Is it a known issue? Is there any solution?

I also encountered this error and I told myself that increasing the allocated memory was a workaround as something must be going wrong under the hood.

If you are using Firebase, it turns out that it is the culprit.

I changed it from "^4.12.1" to "4.6.1" (without the caret symbol) and ran npm install to downgrade it to the said anterior version.

After that, I was able to run ionic cordova build android --prod without encountering the dreaded "heap out of memory" error.

Apparently, 4.12.1 (and perhaps others) has a memory leak, hence the encountered issue.

Hope this helps!
