Encountered a Runtime Error (void 0) is not a function

Ionic Framework ionic-v3
1

I am trying to integrate a plugin : angular2-soap however once the module is included, and I serve ionic, I get an error saying:

Runtime Error (void 0) is not a function

Followed by stack:

TypeError: (void 0) is not a function

I am quite new to ionic and angular 2, so any help would be appreciated.
