ionic-audio | audio player for Ionic | Mobile Application library

I'm trying to run my Ionic app in release mode but am getting a strange error. The app runs fine in non-release mode.

Error: Metadata version mismatch for module /Users/jscotto/Documents/projects/ionic_app/node_modules/ionic-audio/dist/ionic-audio-interfaces.d.ts, found version 4, expected 3

I'm using a plugin called ionic-audio which seems to use Angular 5, my app uses angular 4 but what doesn't make sense is why it would only not work in release build mode.

Any ideas what could be causing this?

I have used ngx-translate in my ionic3 project. It's working fine in browser using ionic serve .But After build and running it in android it doesn't work.It returns only key from the translate file.

I started to get the following error after upgrading my application to the following features. (the code has not changed)

I did not get any errors in the tests, but firebase gave the users the knowledge that they got this error

I did not debug with the firebase console before. Could you help me, please ?

I am new to both Ionic and Cordova. I'm creating a basic app where I'll have some URLs of audio files that I want users to be able to play. These URLs are fetching from web service. Please help me with this query. Thanks.

Edited after trying your answer:

following is the web service response. There is multiple event.Each event has two different audio that I want to play in one section.
