- This is a bug, not a usage question. For questions, please use GitHub Discussions.
- I added a clear and detailed title that summarizes the issue.
- I read what a minimal reproducible example is (https://stackoverflow.com/help/minimal-reproducible-example).
- I included a self-contained, minimal example that demonstrates the issue INCLUDING all the relevant imports. The code run AS IS to reproduce the issue.
Example Code
import asyncio
import nest_asyncio
nest_asyncio.apply() # Allows nested event loops
async def test(user_input):
# Simulate asynchronous streaming of events
async for event in graph.astream(
{"messages": [("user", user_input)]},
config={"configurable": {"thread_id": 42}},
):
print(event)
async def main():
while True:
try:
user_input = input("User: ")
if user_input.lower() in ["quit", "exit", "q"]:
print("Goodbye!")
break
# Call the async function using `await`
await test(user_input)
except Exception as e:
print(f"Error: {str(e)}")
# Fallback behavior
user_input = "What do you know about LangGraph?"
print("User: " + user_input)
break
# Run the main coroutine
await main()Error Message and Stack Trace (if applicable)
