Neil Murphy	b0d0399d34	(issue #5163 ) Append reminder to nest multi-prompt router prompt output in JSON markdown code block, resolving JSON parsing error. (#8709 ) Resolves occasional JSON parsing error when some predictions are passed through a `MultiPromptChain`. Makes [this modification](https://github.com/langchain-ai/langchain/issues/5163#issuecomment-1652220401) to `multi_prompt_prompt.py`, which is much cleaner than appending an entire example object, which is another community-reported solution. @hwchase17, @baskaryan cc: @SimasJan	1 year ago

Alec Flett	f0b0c72d98	add `load()` deserializer function that bypasses need for json serialization (#7626 ) There is already a `loads()` function which takes a JSON string and loads it using the Reviver But in the callbacks system, there is a `serialized` object that is passed in and that object is already a deserialized JSON-compatible object. This allows you to call `load(serialized)` and bypass intermediate JSON encoding. I found one other place in the code that benefited from this short-circuiting (string_run_evaluator.py) so I fixed that too.

aerickson-clt	c7ea6e9ff8	Issue 8081 Fix query results size bug. Other bug: pass vector_field param. (#8085 ) @baskaryan #8081 Likely the reason why the issue occurred is that OpenSearch's default k is 10, so it needs to be specified. Here's a similar question about its cousin ElasticSearch https://discuss.elastic.co/t/elasticsearch-returns-only-10-records-but-the-hit-is-507/136605 I tested this manually and also fixed the same issue in `_default_painless_scripting_query`. In addition, `_default_painless_scripting_query` was not passing the `vector_field` name to a sub call, so I fixed that too. ![image](https://github.com/hwchase17/langchain/assets/32244272/cfb7aad1-f701-49d9-9beb-a723aa276817) I also tested this in the aws opensearch developer tools. ![image](https://github.com/hwchase17/langchain/assets/32244272/24544682-1578-4bbb-9eb5-980463c5b41b) --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	1 year ago

Vasileios Mansolas	e68a1d73d0	Fix Issue #6650 : Enable Azure Active Directory token-based auth access for AzureChatOpenAI (#8622 ) When using AzureChatOpenAI the openai_api_type defaults to "azure". The utils' get_from_dict_or_env() function triggered by the root validator does not look for user provided values from environment variables OPENAI_API_TYPE, so other values like "azure_ad" are replaced with "azure". This does not allow the use of token-based auth. By removing the "default" value, this allows environment variables to be pulled at runtime for the openai_api_type and thus enables the other api_types which are expected to work.

William FH	f81e613086	Fix Async Retry Event Handling (#8659 ) It fails currently because the event loop is already running. The `retry` decorator alraedy infers an `AsyncRetrying` handler for coroutines (see [tenacity line](`aa6f8f0a24/tenacity/__init__.py (L535)`)) However before_sleep always gets called synchronously (see [tenacity line](`aa6f8f0a24/tenacity/__init__.py (L338)`)). Instead, check for a running loop and use that it exists. Of course, it's running an async method synchronously which is not _nice_. Given how important LLMs are, it may make sense to have a task list or something but I'd want to chat with @nfcampos on where that would live. This PR also fixes the unit tests to check the handler is called and to make sure the async test is run (it looks like it's just been being skipped). It would have failed prior to the proposed fixes but passes now.	1 year ago
