The application is built using Meteor (version 2.2)
The error only occurs in production build in Firefox Mobile and Safari Instagram Browser (during loading of the application).
I cannot tell when the error started to occur but I've tested older versions of the application dated a couple of months ago.
I have also tested several versions of Firefox Mobile, so I assume the error is related to incorrect bundling or because of a corrupted Meteor package.
Has anyone come across such an error? What might be the cause? I've run out of ideas on where to look for it.
