For the following code, ```ts import { Hono } from 'hono' import { Ai } from '@cloudflare/ai' import { Bindings } from 'hono/types'; const app = new Hono<{Bindings: Bindings}>() app.get('/', async(c) => { const ai = new Ai(c.env.AI, { sessionOptions: { ctx: c } }); const stream = await ai.run( "@cf/mistral/mistral-7b-instruct-v0.1", { prompt: "where is new york?", stream: true } ) as any; return new Response(stream, { headers: { "content-type": "text/event-stream" } } ); }) export default app ``` I am getting the error show in the attachment. How can I fix this?
