Version

v3.2.0

Reproduction link

https://jsfiddle.net/

Steps to reproduce

Create new Nuxt project.
Install @nuxtjs/sentry >= 3.2.0

Disable sentry in the configuration

sentry: {
    disabled: process.env.NODE_ENV !== 'production',
  }

Open the project in IE 11

What is expected ?

The project should work as in 3.1.0

What is actually happening?

The following error occured : "Proxy is not defined"

ReferenceError: « Proxy » est indéfini
   {
      [functions]: ,
      __proto__: { },
      description: "« Proxy » est indéfini",

   }

Additional comments?

It's due to the new file : sentry-module/lib/sentry.mocked.js that contains new Proxy not supported by IE 11.

CodeSandbox not working in IE it's impossible to give you a reproduction link.
