Describe the Bug

With a durable object, and vitest integration as simple as:

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

And running tests through the vitest integration:

it('fetches feed', async () => {
  const stub = env.MY_DURABLE.get(env.MY_DURABLE.idFromName('main'))
  const res = await expect(() => stub.myCustomFunc()).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.

Why doesn't this error propagate to get handled by Vitest? What is the suggested way to handle thrown errors in implementation in tests?

Please provide any relevant error logs
