[Python] How to return separate JSON responses using FastAPI?

I am not sure if this is part of OpenAPI standard. I am trying to develop an API server to replace an existing one, which is not open source and vendor is gone. One particular challenge I am facing is it returns multiple JSON objects without enclosing them either in a list or array. For example, it returns the following 3 JSON objects as they are, in separate lines:

{"items": 10}
{"order": "shelf", "amount": 100}
{"id": 100, "date": "2022-01-01", "status": "X"}


Not in a list format () or in array [].

For example, the code below returns all 3 objects in an array:

from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def read_root():
data_1 = {"items": 10}
data_2 = {"order": "shelf", "amount": 100}
data_3 = {"id": 100, "date": "2022-01-01", "status": "X"}
return data_1, data_2, data_3


Can anyone help me to get this done with FastAPI?
