Help: Cannot stream anything from workflows after recent update

execute: async ({ mastra, writer, ... }) => {
  const agent = mastra?.getAgent('generalInquiryAgent');
  const stream = await agent?.stream(messages, { runtimeContext });
  await stream!.textStream.pipeTo(writer!); // Text goes to workflow writer
  return { textResponse: await stream!.text };
}

const workflowStream = await run.streamVNext({ inputData: { messages, userData } });
const aiSdkStream = toAISdkFormat(workflowStream, { from: 'workflow' });
return createUIMessageStreamResponse({ stream: aiSdkStream });
