happens both with o3 and o4-mini - first call is ok .. it returns a list of reasoning items all with same id,say ‘rs\_ABCD’ - second call .. same to the first call BUT i provide previous\_response\_id (and a different question of course ).. And i get “error”: { “message”: “Item ‘rs\_ABCD’ of type ‘reasoning’ was provided without its required following item.”, “type”: “invalid\_request\_error”, “param”: “input”, “code”: null } } did not find any help googling .. can someone suggest anything to solve ? thanks enrico P.S. : same flow work with gpt4.1 (that has no reasoning items) ---

as workaround . it looks like that it works if one omits the previous\_response\_id and passes “explicitly” all previous question items as item reference “input”: [ .. { “id”: “x1”, “type”: “item\_reference” }, { “id”: “x2”, “type”: “item\_reference” }, – new question ] still , i would prefer to store a single id (previous\_response\_id ) on my side than the full list ---

well, nope, it does not always work ☹ .. sometime it does, some time same error ---

+1. This seems to happen consistently when files are attached to the container. Here is a minimal example. Let me know if I’m doing something wrong! ```python import io from openai import OpenAI client = OpenAI() # Create sample file csv_content = """X,Y -1,-0.84 -0.8,-0.72 -0.6,-0.56 -0.4,-0.39 -0.2,-0.2 0,0 0.2,0.2 0.4,0.39 0.6,0.56 0.8,0.72 """ csv_file = io.BytesIO(csv_content.encode("utf-8")) # Upload file file = client.files.create(file=csv_file, purpose="user_data") file_id = file.id print(f"File ID: {file_id}") # Generate first response model = "o4-mini" reasoning = {"effort": "medium", "summary": "auto"} response_1 = client.responses.create( model=model, reasoning=reasoning, tools=[ { "type": "code_interpreter", # Create a new container "container": {"type": "auto", "file_ids": [file_id]}, } ], input="Please plot the sample data and tell me what you see.", ) print("\n------\n") print(response_1) # Follow up raises BadRequestError response_2 = client.responses.create( model=model, reasoning=reasoning, input="Thanks!", previous_response_id=response_1.id, ) print("\n------\n") print(response_2) ``` ---

We are experiencing the same issue. In our case, it can be reproduced when there is a reasoning step together with the CodeInterpreter tool. We receive the error when the agent does a hand-off to another agent with different `effort` setting. ---

I found solution!! Do not input reasoning\_id when you use tool as “code\_interpreter” . When I used GPT-5, I experienced a similar issue. So I ran many test cases and eventually discovered a pattern in how the Responses API behaves. I posted this solution. Try making good use of the _item input_. I hope this information was helpful to you.
