IFValidationError: 2 validation errors for DocArrayDoc (missing 'text' and 'metadata' fields) when using DocArrayInMemorySearch with pydantic v2.x

THENDowngrade pydantic to version 1.10.x (e.g., pip install pydantic==1.10.8) or pin pydantic<2 in your project dependencies to avoid the breaking change in the DocArrayDoc schema.

IFImporting from langchain.chains fails with ModuleNotFoundError: No module named 'langchain_core.tracers.langchain_v1'.

THENDowngrade langchain-core to version 0.1.4 (e.g., `pip install langchain-core==0.1.4`) to align with the installed langchain and langchain-community versions. This resolves the missing tracer module that caused the import failure.

IFAfter updating Tenacity to v8.4.0, importing from llama_index.core.schema fails with ModuleNotFoundError: No module named 'tenacity.asyncio'.

THENPin tenacity to version >=8.2.0,<8.4.0 in your dependencies. If you have control over the llama-index source code, update import statements from 'from tenacity.asyncio import AsyncRetrying' to 'from tenacity import AsyncRetrying'.

IFlitellm fails to import with ImportError: cannot import name 'ResponseTextConfig' from 'openai.types.responses.response' when openai version is >=1.100.0

THENPin the openai package version to 1.99.9 in your requirements file (e.g., openai==1.99.9) until litellm releases a compatible update. This resolves the import error immediately.

IFImporting llama_index after installing langchain version 0.0.293 raises ModuleNotFoundError: No module named 'langchain.embeddings.base'.

THENDowngrade langchain to version 0.0.292 by running `pip uninstall langchain==0.0.293` then `pip install langchain==0.0.292`. Alternatively, use a conditional import to handle moved modules if you cannot control the langchain version.

IFDocArrayInMemorySearch raises ValidationError with 'Field required' for 'text' and 'metadata' under pydantic v2

THENDowngrade pydantic to version 1.10.x by running 'pip install pydantic==1.10.8'. This resolves the incompatibility until LangChain officially supports pydantic v2.

IFPoetry fails to add llama-index due to Python version conflict: the project's supported Python range is not compatible with llama-index's Python requirement (>=3.8.1,<3.12).

THENUpdate the project's pyproject.toml to set Python version constraint to a range that is a subset of the package's required range (e.g., '>=3.10,<3.12' for Python 3.11), run 'poetry lock --no-update', then 'poetry install', and finally 'poetry add llama-index@latest'.
