How can I get stream response?

[qcsusu]

I load the json file
import json
from langflow.graph.graph.base import Graph
from langflow.processing.process import run_graph
import uuid

Generate a valid UUID

valid_uuid = str(uuid.uuid4()) # This will generate a valid UUID string

Load your flow JSON

with open("Basic Prompting.json", "r") as f:
flow_json = json.load(f)

user_id = flow_json.get("user_id") # Extract user_id from root
graph_data = flow_json["data"]

Build the Graph with user_id

graph = Graph.from_payload(graph_data, user_id=user_id,flow_id=valid_uuid)

Run the graph (async)

import asyncio
async def main():
results = await run_graph(
graph=graph,
input_value="Hello, World!",
input_type="chat",
output_type="chat",
session_id="my_session_123"
)
print(results)

asyncio.run(main())
By using this ,I can get an invoke response.I want to get a stream response,how to do it? Please show me the codes.
