Fix for LangGraph Compatibility Issues: ExecutionInfo ImportError with langgraph-prebuilt

Affected Issues

#7420 — RuntimeError: Cannot patch execution_info before it has been set (on LangGraph Cloud)

#7404 — ImportError: cannot import name 'ExecutionInfo' from 'langgraph.runtime' (and sometimes 'ServerInfo')

Symptoms

When installing recent versions of langgraph, you may encounter one (or both) of the following errors:

1. RuntimeError (common on LangGraph Cloud):

RuntimeError: Cannot patch execution_info before it has been set on LangGraph Cloud executor 0.7.96

2. ImportError (when importing agents, ToolNode, create_react_agent, etc.):

ImportError: cannot import name 'ExecutionInfo' from 'langgraph.runtime'
# or
ImportError: cannot import name 'ServerInfo' from 'langgraph.runtime'

The stack trace usually points to:

langgraph/prebuilt/tool_node.py

langgraph/prebuilt/chat_agent_executor.py

langchain/agents/factory.py

Root Cause

langchain and langgraph automatically installs the latest langgraph-prebuilt package.

Starting with langgraph-prebuilt==1.0.9 (released alongside langgraph==1.1.5), the prebuilt package began importing new runtime classes (ExecutionInfo, ServerInfo) and added stricter logic around patch_execution_info.

These changes are not compatible with langgraph==1.0.x or the current LangGraph Cloud executor (0.7.96). This creates a version mismatch that breaks both local imports and cloud deployments.

Solution (Workaround)

Downgrade and pin langgraph-prebuilt to version 1.0.5, along with compatible versions of the core LangGraph packages.

Recommended Stable Package Versions

langchain==1.2.0
langchain-core==1.2.5
langchain-openai==1.1.6
langgraph==1.0.5
langgraph-checkpoint==3.0.1
langgraph-prebuilt==1.0.5
langgraph-sdk==0.3.1
langsmith==0.5.0

Installation

Using pip (recommended for quick fix):

pip install \
  langchain==1.2.0 \
  langchain-core==1.2.5 \
  langchain-openai==1.1.6 \
  langgraph==1.0.5 \
  langgraph-checkpoint==3.0.1 \
  langgraph-prebuilt==1.0.5 \
  langgraph-sdk==0.3.1 \
  langsmith==0.5.0

For production / reproducibility, add these pins to your requirements.txt:

langgraph==1.0.5
langgraph-prebuilt==1.0.5
langgraph-checkpoint==3.0.1

For LangGraph Cloud Deployments

Ensure the exact versions above (especially langgraph-prebuilt==1.0.5) are listed in your project's dependency configuration. This prevents the cloud from pulling newer, incompatible prebuilt packages.

Verification

After installation:

Clear pip cache if needed: pip cache purge

Test the imports:

Run your graph locally and redeploy to LangGraph Cloud.

Both the ImportError and RuntimeError should be resolved.

Important Note

This is a temporary workaround. The root issue stems from a breaking change in langgraph-prebuilt that was not properly version-gated. A permanent fix is expected once:

langgraph-prebuilt receives a proper major version bump, or

LangGraph Cloud updates its executor runtime.
