Vitest `Failed to pop isolated storage stack frame` when error thrown

With a durable object as simple as:

export class FeedStorage extends DurableObject {
  async test() { throw new Error("My impl is broken") }
}

export class FeedStorage extends DurableObject {
  async test() { throw new Error("My impl is broken") }
}

And running tests through the vitest integration:

it('fetches feed', async () => {
  const stub = env.FEED_STORAGE.get(env.FEED_STORAGE.idFromName('main'))
  const res = await expect(() => stub.test()).rejects.toThrowError()
})

it('fetches feed', async () => {
  const stub = env.FEED_STORAGE.get(env.FEED_STORAGE.idFromName('main'))
  const res = await expect(() => stub.test()).rejects.toThrowError()
})

I end up with Vitest caught 1 unhandled error during the test run., and Failed to pop isolated storage stack frame I'd expect this to be propagated up through rpc as it is mentioned in the docs here so vitest can handle it. What is the suggested way to handle thrown errors in implementation in tests?

RPC of a Service Binding / DO: Adding middleware?

I don't see any references in the docs so I assume the answer is no, but I'm wondering if it's possible to add middleware in any way to Durable Object RPC classes or Service Bindings? I could envision a potential userland solution, but I'm curious if there is something that already exists?

Specifying a `-- <command>` or `--proxy` is deprecated and will be removed

Recently noticed this warning when running wrangler pages dev -- vite:

[WARNING] Specifying a `-- <command>` or `--proxy` is deprecated and will be removed in a future version of Wrangler.
 
   Build your application to a directory and run the `wrangler pages dev <directory>` instead.
   This results in a more faithful emulation of production behavior.

I'm curious what the suggestion is for users of vite or similar framework where there is no directory in dev mode?

Point to remote r2 bucket when running pages dev locally?

Is there any way to point a binding to a remote r2 bucket when running pages dev locally? From the docs on the --r2=BINDING_NAME flag, it seems to only support a local bucket?

Preview branch, custom domain not supported

When adding a custom domain for a preview branch using external DNS, this page states that custom domains are not supported for external DNS. https://developers.cloudflare.com/pages/how-to/custom-branch-aliases/ Why does this limitation exist? Are there any ways to work around this functionality?

Is there any way to temporarily disable mutations?

My goal is to move into a read-only mode temporarily. I'm thinking anything could be fine as a short term solution. 1. Throw an explicit error when mutations try to be called 2. Procedure not found error 3. Stop support POST requests?

Ignore paths in pages `functions` directory

Are there any prefixes that will allow me to ignore files in the functions directory, so I can locate my non-route logic adjacent to my routes? Other frameworks often use an underscore prefix for instance If not, is there a way to specify multiple directories for wrangler to watch during wrangler pages dev? Putting my server code in ./server doesn't trigger auto-refreshes...

See logs when using unstable_dev?

When using unstable_dev, I can't seem to find any docs on how to see / inspect logs or errors coming from the worker or durable objects. How can I see the logs?

Determine if built by wrangler dev or wrangler deploy

I have a worker which when running locally will proxy to a Vite server, but when deployed will be a Workers Site using kvAssetHandler. Is there any default way to determine which it was built for? Or do I need to mess with .dev.vars?
