@bugsnag/plugin-vue is throwing: TypeError: Cannot read properties of undefined (reading 'errorHandler')

[brunomonteiro-asknicely]

Describe the bug

The bugsnag-vue.js file is using Vue 2 syntax in a Vue 3 project due to a problematic if check. This then causes Bugsnag to try to access Vue.config in a Vue 3 project where global config is not available anymore.

This issue was also reported here, but it was closed due to lack of activity.

Problematic line seems to be this one. I believe a simple update to check Vue.version should fix it.

Steps to reproduce

1. Install Vue 3 via package.json
2. Import Vue 3 via CDN in the html file
3. Follow the instructions to install Bugsnag in a Vue app

Environment

• Bugsnag version: 7.23.0
• Browser framework version (if any): Vue 3

Example Repo

• [X] Create a minimal repository that can reproduce the issue
• [X] Link to it here: https://codesandbox.io/p/devbox/xenodochial-bose-qvvrvp

Just as an update: if I go to my node_modules folder and manually change the code to

if (this.Vue.version[0] === '2') {

it works fine!

Hi @brunomonteiro-asknicely

Thanks for sharing this workaround.

We now have an item on our backlog aimed at fixing this issue. While we don't have a clear ETA on the release of this functionality, we will be sure to update you once we have more information to share!

Thanks @clr182 ! Until this fix is released, we can't really use Bugsnag since the change in node_modules is not a realistic solution for our CI environment. Will keep an eye here and appreciate the update when that is done.
