Durable Object RPC is not yet supported between multiple 'wrangler dev' sessions

[lorenzodejong]

Hi! I'm trying to setup a Hono/Vite project for Cloudflare Pages including support for Durable Objects. However in this setup I noticed that the DO should actually be running as a separate Worker, and referenced using the script_name configuration in the wrangler.toml (similar to #190).

However when running this, I'm receiving the following error:

Cannot access 'MyDurableObject#set' as Durable Object RPC is not yet supported between multiple 'wrangler dev' sessions.

My wrangler.toml looks like the following:

name = "api"
main = "src/api/index.ts"
compatibility_date = "2024-11-29"

compatibility_flags = [ "nodejs_compat_v2" ]

[[durable_objects.bindings]]
name = "MY_DURABLE_OBJECT"
class_name = "MyDurableObject"
script_name = "my-do"

And my vite.config.ts:

import build from '@hono/vite-cloudflare-pages';
import devServer from '@hono/vite-dev-server';
import adapter from '@hono/vite-dev-server/cloudflare';
import { TanStackRouterVite } from '@tanstack/router-plugin/vite';
import viteReact from '@vitejs/plugin-react';
import path from 'path';
import { defineConfig } from 'vite';

const resolve = {
  alias: {
    '@': path.resolve(__dirname, './src'),
  },
};

export default defineConfig(async ({ mode }) => {
  if (mode === 'client') {
    return {
      plugins: [
        viteReact(),
        TanStackRouterVite({
          routesDirectory: 'src/routes',
          generatedRouteTree: 'src/routeTree.gen.ts',
        }),
      ],
      resolve,
      server: {
        port: 3000,
        proxy: {
          '/api': {
            target: 'http://localhost:9000',
            changeOrigin: true,
            rewrite: (path: string) => path.replace(/^\/api/, ''),
          },
        },
      },
    };
  }

  return {
    plugins: [
      devServer({
        entry: 'src/api/index.ts',
        adapter,
      }),
      build(),
    ],
    resolve,
    server: {
      port: 9000,
    },
  };
});

Do I have an oversight and/or misconfiguration or should this configuration work?
