Plugin execution not working anymore about langchain

[TJKlein]

As a side note - the LangGraph implementation is working as expected

from langgraph.prebuilt import chat_agent_executor
from langchain_core.messages import HumanMessage

agent_executor = chat_agent_executor.create_tool_calling_executor(
    llm, tools)

response = agent_executor.invoke({"messages": [HumanMessage(content="""What are some t-shirts at klarna?""")]})

response['messages'][-1].content

producing:

'Here are some t-shirts available on Klarna:\n\n
