Vincent Brouwers	67662564f3	langchain[patch]: Fix `config` arg detection for wrapped lambdarunnable (#14230) ... **Description:** When a RunnableLambda only receives a synchronous callback, this callback is wrapped into an async one since #13408. However, this wrapping with `(*args, **kwargs)` causes the `accepts_config` check at [/libs/core/langchain_core/runnables/config.py#L342](ee94ef55ee/libs/core/langchain_core/runnables/config.py (L342)) to fail, as this checks for the presence of a "config" argument in the method signature. Adding a `functools.wraps` around it, resolves it.	7 months ago
Hendrik Hogertz	e6862e6e7d	Fix Azure Openai function calling in streaming mode (#13768) ... - **Description**: This PR addresses an issue with the OpenAI API streaming response, where initially the key (arguments) is provided but the value is None. Subsequently, it updates with {"arguments": "{\n"}, leading to a type inconsistency that causes an exception. The specific error encountered is ValueError: additional_kwargs["arguments"] already exists in this message, but with a different type. This change aims to resolve this inconsistency and ensure smooth API interactions. - **Issue**: None. - **Dependencies**: None. - **Tag maintainer**: @eyurtsev This is an updated version of #13229 based on the refactored code.

Jeremy Naccache	a14cf87576	core[patch]: Add **kwargs to Langchain's dumps() to allow passing of json.dumps() … (#10628) ... …parameters. In Langchain's `dumps()` function, I've added a `**kwargs` parameter. This allows users to pass additional parameters to the underlying `json.dumps()` function, providing greater flexibility and control over JSON serialization. Many parameters available in `json.dumps()` can be useful or even necessary in specific situations. For example, when using an Agent with return_intermediate_steps set to true, the output is a list of AgentAction objects. These objects can't be serialized without using Langchain's `dumps()` function. The issue arises when using the Agent with a language other than English, which may contain non-ASCII characters like 'é'. The default behavior of `json.dumps()` sets ensure_ascii to true, converting `{"name": "José"}` into `{"name": "Jos\u00e9"}`. This can make the output hard to read, especially in the case of intermediate steps in agent logs. By allowing users to pass additional parameters to `json.dumps()` via Langchain's dumps(), we can solve this problem. For instance, users can set `ensure_ascii=False` to maintain the original characters. This update also enables users to pass other useful `json.dumps()` parameters like `sort_keys`, providing even more flexibility. The implementation takes into account edge cases where a user might pass a "default" parameter, which is already defined by `dumps()`, or an "indent" parameter, which is also predefined if `pretty=True` is set. --------- Co-authored-by: Erick Friis <erick@langchain.dev>	7 months ago

ggeutzzang	3749af79ae	DOCS: fixed error in the docstring of RunnablePassthrough class (#13843) ... This pull request addresses an issue found in the example code within the docstring of `libs/core/langchain_core/runnables/passthrough.py` The original code snippet caused a `NameError` due to the missing import of `RunnableLambda`. The error was as follows: ``` 12 return "completion" 13 ---> 14 chain = RunnableLambda(fake_llm) | { 15 'original': RunnablePassthrough(), # Original LLM output 16 'parsed': lambda text: text[::-1] # Parsing logic NameError: name 'RunnableLambda' is not defined ``` To resolve this, I have modified the example code to include the necessary import statement for `RunnableLambda`. Additionally, I have adjusted the indentation in the code snippet to ensure consistency and readability. The modified code now successfully defines and utilizes `RunnableLambda`, ensuring that users referencing the docstring will have a functional and clear example to follow. There are no related GitHub issues for this particular change. Modified Code: ```python from langchain_core.runnables import RunnablePassthrough, RunnableParallel from langchain_core.runnables import RunnableLambda runnable = RunnableParallel( origin=RunnablePassthrough(), modified=lambda x: x+1 ) runnable.invoke(1) # {'origin': 1, 'modified': 2} def fake_llm(prompt: str) -> str: # Fake LLM for the example return "completion" chain = RunnableLambda(fake_llm) | { 'original': RunnablePassthrough(), # Original LLM output 'parsed': lambda text: text[::-1] # Parsing logic } chain.invoke('hello') # {'original': 'completion', 'parsed': 'noitelpmoc'} ``` --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	7 months ago
