appendClientMessage fail when implementing message persistence

[tha-hammer]

Using new AI SDK to 'hack' the Vercel "out of the box" AI UI (wow that would sound like total gobbledygook to just about 99.99% of the world I think, lol)

Error:
/app/(chat)/api/chat/route.ts:7:3
Type error: Module '"ai"' has no exported member 'appendClientMessage'.
5 | smoothStream,
6 | streamText,

7 | appendClientMessage
| ^
8 | } from 'ai';
9 |
10 |
 ELIFECYCLE  Command failed with exit code 1.
Error: Command "pnpm run build" exited with 1

Code:

import {
type Message,
convertToCoreMessages,
createDataStreamResponse,
smoothStream,
streamText,
appendClientMessage
} from 'ai';

I quintuple checked my spelling. Added an installer package just in case...

Install "extras" pnpm add @ai-sdk/anthropic @ai-sdk/openai zod ai

I'm just an idiot right... this is something easy?

Are you using the latest library versions?
