Unable to run timeline demo page

[MattIGolden]

Description

I am trying to open the timeline demo but I get an error page every time I try. This is the only page that isn't working as it should for me. All the other (detail panel, empty state, etc.) are fine.
Here are some steps I took to fix this issue.

• Updated the NR1 CLI

• Double checked to make sure my fork was up to date with upstream repo

• Been sure to nom install in both the root and demo directories

• I’ve closed and reopened the nerdlet via the launcher on the homepage

• And finally restarted my computer and started up the project again and still I’m getting the following errors when I try to open the timeline page

Steps to Reproduce

Go into the nr1-community nerdpack and navigate to the timeline demo.

Expected Behaviour

It should look like the rest of the other pages do when I click into it.

Relevant Logs / Console output

There are five errors in the console. A detailed log is below.

React will try to recreate this component tree from scratch using the error boundary you provided, t

- Warning: t: Error boundaries should implement getDerivedStateFromError(). In that method, return a state update to display an error message or fallback UI.
- Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method.

@danielgolden can you look into this next week?

@tangollama I think the issue here is that he doesn't have any account data for the timeline component to use. It loads fine for me, but in my case it's using demotron v2. Is there any way around this?
