Unpredictable behavior from the network agent when using @mastra/ai-sdk beta.1.

export const orchestrationAgent = new Agent({
  id: 'orchestration-agent',
  name: 'Orchestration Agent',
  description: `Main orchestration agent that can orchestrate other agents.`,
  instructions: `
     You are a main orchestration agent that can orchestrate other agents.
     You can run:
     - weatherAgent to get weather information
     - mathAgent to sum two numbers
     `,
  model: DEFAULT_MODEL,
  agents: {
    weatherAgent,
    mathAgent,
  },

 //api/route.ts


const agent = mastra.getAgent("orchestrationAgent");

export async function POST(req: Request) {
  const { messages, memory} = await req.json();
    const stream = await agent.network(messages, {
      memory: {
        thread: memory.thread,
        resource: memory.resource,
      },
    });
  
    return createUIMessageStreamResponse({
      stream: toAISdkStream(stream, { from: "network" }),
