• The string concatenation is incomplete. This creates a string literal "Found AIMessages with tool_calls that do not have a corresponding ToolMessage. " without including the f-string that follows it. The fix correctly combines them into a single string expression.

The import path for AgentState has changed from langgraph.prebuilt.chat_agent_executor to langchain.agents. Please verify that this import path is correct and that the AgentState class in langchain.agents has the same interface and behavior as expected. This could be a breaking change if the classes are not compatible.
