Update chat example in server.mdx to work properly

[jhammarstedt]

Fixing some errors in the demo to make the chat example run:

• proper parsing of openai messages,
• make message_id to string to avoid validation error
• set the openai_key directly in the client
• include a test request

Hi @jhammarstedt this looks great! Would you mind rebasing this so we can merge?

Done! :) @tylerslaton

@jhammarstedt This looks really good!

Would you mind just removing the comments from the JSON code examples so that all the syntax there is correct and easily copyable?

It may help to clarify what lines you're adding before a code block.

Here's an example of how that might look (expand/collapse) BEFORE ## Step 2 – Add package to dojo dependencies Open `apps/dojo/package.json` and add the package `@ag-ui/openai-server`: ```json { "name": "demo-viewer", "version": "0.1.0", "private": true, "scripts": { "dev": "next dev", "build": "next build", "start": "next start", "lint": "next lint" }, "dependencies": { "@ag-ui/agno": "workspace:*", "@ag-ui/langgraph": "workspace:*", "@ag-ui/mastra": "workspace:*", "@ag-ui/middleware-starter": "workspace:*", "@ag-ui/server-starter": "workspace:*", "@ag-ui/server-starter-all-features": "workspace:*", "@ag-ui/vercel-ai-sdk": "workspace:*", "@ag-ui/openai-server": "workspace:*", // Add this line ... rest of package.json } ``` AFTER ## Step 2 – Add package to dojo dependencies Open `apps/dojo/package.json` and add the package `@ag-ui/openai-server`: ```json { "name": "demo-viewer", "version": "0.1.0", "private": true, "scripts": { "dev": "next dev", "build": "next build", "start": "next start", "lint": "next lint" }, "dependencies": { "@ag-ui/openai-server": "workspace:*" } } ``` or even this: ## Step 2 – Add package to dojo dependencies Open `apps/dojo/package.json` and add the package `@ag-ui/openai-server`: ```json { "dependencies": { "@ag-ui/openai-server": "workspace:*" } } ```

It's too bad there's not some way to annotate code in GitHub outside code blocks in a way that isn't copyable.
