Langserve Quickstart Example Not found error

[Pavan-628]

I am following the langserve quickstart example. here's the link

https://python.langchain.com/docs/get_started/quickstart/#serving-with-langserve

However this example fails with detail: Not found error when launching the agent with python serve.py

Some body pls help

[javaeeeee]

The curl request looks like:

curl http://localhost:8000/chain/invoke -d '{"input":{"language": "Italian", "text": "hi"}}' -H 'Content-Type: application/json'

First, you need to add /invoke, '/stream' to the URL and second, the body of the request contains input field.

The explanation can be found in a blog post https://blog.langchain.dev/introducing-langserve/.
