No build or start errors, but Docs won't render

[sweeneyskirt-sl]

I am trying to upgrade to 2.0.0-beta.4 so I can take advantage of the new trailingSlash property. I am able to build (with a couple warnings:

<w> [webpack.cache.PackFileCacheStrategy] Skipped not serializable cache item 'Compilation/modules|/Users/nancysweeney/GH/sauce-docs/node_modules/tiny-warning/dist/tiny-warning.esm.js': No serializer registered for ConstDependency
<w> while serializing webpack/lib/cache/PackFileCacheStrategy.PackContentItems -> webpack/lib/NormalModule -> Array { 3 items } -> ConstDependency
<w> [webpack.cache.PackFileCacheStrategy] Skipped not serializable cache item 'Compilation/modules|/Users/nancysweeney/GH/sauce-docs/node_modules/tiny-invariant/dist/tiny-invariant.esm.js': No serializer registered for ConstDependency
<w> while serializing webpack/lib/cache/PackFileCacheStrategy.PackContentItems -> webpack/lib/NormalModule -> Array { 3 items } -> ConstDependency

And running yarn start seems to go fine, with the Client compiled successfully message, and the site opens on the launch page at localhost:3000. However, when I click to actually open the Docs site, the page hangs indefinitely. If I refresh, I get a blank screen. Inspecting the page produces this error:

Can anyone help?

Maybe try yarn clear && yarn install?

Also worth trying deleting your lockfile and re-generating it
