Previously any token that was not a parseable JWT failed validation with "Invalid access token: expected JWT with at least 2 dot-separated parts". Token introspection is now best-effort: `is_token_expired` returns `False` when the token is not a parseable JWT, and the settings validator only extracts `client_id` when the token is a parseable JWT. Added `try_parse_access_token` helper in `uipath.llm_client.settings.platform.utils`. + ## [1.13.0] - 2026-05-27 ### Added diff --git a/packages/uipath_langchain_client/CHANGELOG.md b/packages/uipath_langchain_client/CHANGELOG.md index e0fade7..2739ff3 100644 --- a/packages/uipath_langchain_client/CHANGELOG.md +++ b/packages/uipath_langchain_client/CHANGELOG.md @@ -2,6 +2,11 @@ All notable changes to `uipath_langchain_client` will be documented in this file. +## [1.13.1] - 2026-06-09 + +### Fixed +- Picks up the core `uipath-llm-client` 1.13.1 fix allowing non-JWT access tokens (e.g. opaque UiPath reference tokens) as `UIPATH_ACCESS_TOKEN`, so LangChain clients built on `PlatformSettings` no longer fail validation with "Invalid access token: expected JWT with at least 2 dot-separated parts". + ## [1.13.0] - 2026-05-27 ### Changed diff --git a/packages/uipath_langchain_client/pyproject.toml b/packages/uipath_langchain_client/pyproject.toml index feb4713..d640dad 100644 --- a/packages/uipath_langchain_client/pyproject.toml +++ b/packages/uipath_langchain_client/pyproject.toml @@ -6,7 +6,7 @@ readme = "README.md" requires-python = ">=3.11" dependencies = [ "langchain>=1.2.15,<2.0.0", - "uipath-llm-client>=1.13.0,<2.0.0", + "uipath-llm-client>=1.13.1,<2.0.0", ] [project.optional-dependencies] diff --git a/packages/uipath_langchain_client/src/uipath_langchain_client/__version__.py b/packages/uipath_langchain_client/src/uipath_langchain_client/__version__.py index 96b1a7b..6cdfc11 100644 --- a/packages/uipath_langchain_client/src/uipath_langchain_client/__version__.py +++ b/packages/uipath_langchain_client/src/uipath_langchain_client/__version__.py @@ -1,3 +1,3 @@ __title__ = "UiPath LangChain Client" __description__ = "A Python client for interacting with UiPath's LLM services via LangChain." -__version__ = "1.13.0" +__version__ = "1.13.1" diff --git a/src/uipath/llm_client/__version__.py b/src/uipath/llm_client/__version__.py index b7fb238..d206086 100644 --- a/src/uipath/llm_client/__version__.py +++ b/src/uipath/llm_client/__version__.py @@ -1,3 +1,3 @@ __title__ = "UiPath LLM Client" __description__ = "A Python client for interacting with UiPath's LLM services." -__version__ = "1.13.0" +__version__ = "1.13.1" diff --git a/src/uipath/llm_client/settings/platform/settings.py b/src/uipath/llm_client/settings/platform/settings.py index eaed4f8..7c4f63c 100644 --- a/src/uipath/llm_client/settings/platform/settings.py +++ b/src/uipath/llm_client/settings/platform/settings.py @@ -30,7 +30,10 @@ from uipath.llm_client.settings.base import UiPathAPIConfig, UiPathBaseSettings from uipath.llm_client.settings.constants import ApiType, RoutingMode -from uipath.llm_client.settings.platform.utils import is_token_expired, parse_access_token +from uipath.llm_client.settings.platform.utils import ( + is_token_expired, + try_parse_access_token, +) class PlatformBaseSettings(UiPathBaseSettings): @@ -81,8 +84,11 @@ def validate_environment(self) -> Self: "Access token is expired.
