TypeError [ERR_INVALID_STATE]: Invalid state: The ReadableStream is locked

[97revenge]

Description

All the code is based on the Vercel IA SDK documentation, I'm using the createGoogleGenerativeAI provider instance with my API key and everything is fine, but whenever I need a return on the client side with new StreamingTextResponse(result.toAIStream( )) return this error:

my AI response is not compromised but the available stream is locked...

Code example

import { StreamingTextResponse, streamText, StreamData } from "ai";

import { NextRequest } from "next/server";

import { createGoogleGenerativeAI } from "@ai-sdk/google";

export const dynamic = "force-dynamic";

export const POST = async (req: NextRequest) => {
  const data = await req.json();
 

  const google = createGoogleGenerativeAI({
    apiKey: process.env.GOOGLE_API_KEY!,
    // custom settings
  });

  const model = google("models/gemini-1.5-pro-latest");

  const result = await streamText({
    model,
    prompt: "Hello , you you doing? "
    seed: 5,
  });

  let message = "";

  for await (const item of result.textStream) {
    console.log(item);
    message = item;
  }

  if (!result) {
    console.log("error !!! ");
  }

  return new StreamingTextResponse(result.toAIStream());
};
