InvalidRequestError with langchain agent with retrieval tool

I am trying to build a retriever agent using langchain mainly following their tutorial (Agent with retrieval tool). I have used both the high-level api and built from components. At the very last line , when I call the agent, it gives me this error: InvalidRequestError: ‘protocol details’ does not match ‘[1]{1,64}$’ - ‘’

The last part of code looks like this:
from langchain.agents import AgentExecutor
agent_executor = AgentExecutor(
**agent=agent, **
**tools=tools, **
**memory=memory, **
**verbose=True, **

result = agent_executor({“input”: “Hi, I’m Bob”})

Can’t find anything on the internet resembling this message. Any help would be appreciated.
openai ver. 0.28.1
langchaine 0.0.332
python 3.10 and 3.11 tested
openai models 3.5 turbo and 4

This is part of retrieval tool and the thing with naming convention of these is that there is supposed to be no space between tool name like ‘Tool 1’ should be ‘Tool_1’.
This will resolve the issue. OpenAI or Langchain hasn’t mentioned this anywhere.

Thanks. It worked. :+1: Name was the issue.
