Uncaught TypeError: Cannot read property 'appId' of null

[summera]

Version info

• intercom-rails version: 0.3.5
• Rails version: 5.1.4

Expected behavior

No error.

Actual behavior

Receiving Uncaught TypeError: Cannot read property 'appId' of null in console in one of our testing environments and then the Messenger does not show. What's interesting, is this is not happening in our production environment. The testing environment and production environment are using separate Intercom apps. I'm using Turbolinks and it seems to happen on a Turbolinks page load (rather than a full page load) and when using the back button. This is happening in Chrome 67.0.3396.99. I've tried clearing cache and cookies for the domain and that doesn't fix. I don't see the error in Chrome Incognito mode or in Firefox.

I have the same issue.

In my case the issue persist for both environment.

Any ideas?

[summera]

@SeanHealy33 any idea what's going on here?

[adnan-kamili]

This happens when I call (window as any).Intercom('shutdown'); in my angular app

[andychongyz]

Any update?

I just experienced this as well. Our Intercom is installed via Segment 1.1

I have been seeing this as well. What I think is happening is that the shutdown call runs while Intercom process is loading (not 100% certain). My current work around is to add a delay to the shutdown:

setTimeout( () => {window.Intercom('shutdown')}, 600)
