is this happening every time? how can I replicate this

[tzengshinfu]

Hi, HenryHengZJ: It might be challenging to reproduce, as I'm using Ollama Embeddings (Local Ollama) + ChatOllama (Local Ollama) + Postgres Vector Store + Conversational Retrieval QA Chain.

However, I've observed that the API endpoint used in the UI part is different from the one used when calling the API directly.

The payload parameters are also different.

And in the UI part, only the Streaming Response provides the correct answer.

The answer obtained by directly using the API is incorrect.

I followed the suggestion to pass the sessionId, but the results are still different. (The user will only ask questions to Flowise through a third-party webhook, but the API's answers should match those of the UI.)
