Dify version

0.6.8

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

I used the example code to make a call to the chat app built in dify (the dify is installed with docker compose)

My data as follows:
const dataNew = {
inputs: {},
query: "hello",
response_mode: "streaming",
conversation_id: "",
user: "abc-123",
}

✔️ Expected Behavior

For a normal streaming service, the streaming response should come in chunks, words by words. Like following

❌ Actual Behavior

Altho the response format is in text/event-stream, the event stream actually came in once, not in chunks.
