error "Application error" when clicking website menu -> "Account+"

[gobengo]

Discovered While Testing:

• ensuring users see correct UI upon login #2218

Reproduction Steps:

• log into https://web3.storage (create a new account if needed)
• go to https://web3.storage/account/
• make your window small so you see the mobile ui

* click the squiggly menu icon in top right. You should see menu. * click "Account+"

Expected Behavior:

• either
  • I am taken to an account page
  • or a nested menu opens there where I can click 'plans and pricing' (thats what I was trying to do)

Actual Behavior:

• page replaces with grey background and shows error: "Application error: a client-side exception has occurred (see the browser console for more information)
• js console error:

whoops! I replied on the wrong ticket. This one is still needed. Disregard the above comment.

This has been validated in staging by clicking the collapsible sections in the mobile nav menu.

Regression was performed to ensure that we're still properly firing the "accordion_opened" event for Simple Analytics.
