TypeError: Cannot convert undefined to object

[noesting]

Hello,

I'm developing a WebApp using Ionic 3 and Meteor. When I connect to my page i get the following error:

TypeError: Cannot convert undefined to object

I use the npm Package meteor-client-bundler (https://github.com/Urigo/meteor-client-bundler). Searching for a solution led me here Urigo/Ionic2CLI-Meteor-WhatsApp#124 and here Urigo/meteor-client-bundler#41 (comment)

So I think this might be an issue in core-js.

Thanks in advance for your help.

Some information about my system:

Meteor Version:

meteor --version
Meteor 1.6

That looks like a bug (#300) which was fixed in [email protected], however, I'm not sure without a reproducible example.

My core-js version is 2.5.1

The problem were old browser versions. I got the issue in the following Browsers

• Firefox 52.0.2 (64-Bit)
• Chromium Version 53.0.2785.143
• Opera 12.16
• Edge 38.x

After updating my browsers it seems to work except for IE 11.

As I wrote, I can't say anything without a reproducible example. So I close it as can't reproduce.
