Devtools fails on vanilla template

[qbzzt]

Steps to reproduce

1. Run the vanilla template:

   pnpm create mud@main app
   # I selected vanilla, but it shouldn't matter
   cd app; pnpm dev

2. In a browser window (Chrome on MacOS), go to http://localhost:3000.

3. Click. Increment.

4. Look right for the dev tools.

Expected behavior

I expect information in dev tools to be updated.

Error

In the dev tools:
