Describe your problem

with Agent sessions, I have a simple loop of (begin(with id as input parameter), interact, generate( to just print id)). I want each session having a separate id that I pass. the issue is that I need to send 3 requests to get my answer instead of two. This is how I am doing it: to generate session_id: curl -X POST "https://******/api/v1/agents/*******/completions" -H "accept: application/json" -H "Authorization: ********" -H "Content-Type: application/json" -d "{\"id\":10}"

to get the id from LLM: curl -X POST "https://***************/api/v1/agents/*************/completions" -H "accept: application/json" -H "Authorization: ****************" -H "Content-Type: application/json" -d "{\"session_id\": \"e8065324739d11f092beaabd83257d03\",\"question\":\"what's the id?\",\"stream\":false}"

and this would be the output: data:{"code": 0, "message": "", "data": {"answer": "Hi, how can I help you?", "reference": {}, "id": "40fd0431-34fb-4bd9-9380-4e603b01a612", "session_id": "4026e73c73a111f088e1aabd83257d03"}}

running the same request again:

data:{"code": 0, "message": "", "data": {"answer": "*'Generate_0'* is running...🕞", "running_status": true}}

data:{"code": 0, "message": "", "data": {"answer": "The ID is 13.", "reference": {}, "id": "3f55eadb-e536-4c6d-88ca-ceaa77841c95", "session_id": "4026e73c73a111f088e1aabd83257d03"}}

which is correct but why after 2nd try?

Hi @raminmardani! I'm Dosu and I’m helping the ragflow team.

This is expected behavior in RAGFlow. The first request with a new session initializes the agent and always returns the greeting or prologue from the 'Begin' component, regardless of your question. Only after this initial greeting does the workflow process your actual query, which is why you see the correct answer after the second or third request. This multi-step flow (session creation → greeting → actual answer) is by design and not a bug—it's how the agent session architecture is structured, and changing it would require a fundamental redesign. This pattern is documented and has been discussed by maintainers and other users as the current expected flow (source, source).

To reply, just mention @dosu.

The first is the start message. The second is the actual answer. Try web ui, that might help you understand.
