Run Flow From json Error

[LeeMoofon0222]

Hi,
I'm wonder why I get this error when I use run_flow_from_json.

try:
    response = run_flow_from_json(flow=flow_path,
                                input_value=prompt,
                                fallback_to_env_vars=True,
                                tweaks=TWEAKS)
except Exception as e:
    st.error(f"An error occurred while calling the API: {str(e)}")
    st.error(f"Error type: {type(e).__name__}")
    st.error(f"Full error details: {e}")
    import traceback
    st.error(f"Traceback: {traceback.format_exc()}")

Error:

An error occurred while calling the API: 'data'

Error type: KeyError

Full error details: 'data'

Traceback: Traceback (most recent call last): File "Chatbot_json.py", line 426, in <module> response = run_flow_from_json(flow=flow_path, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\Moofon\桌面\Causal_Chatbot\causal_chatbot\Lib\site-packages\langflow\load\load.py", line 117, in run_flow_from_json graph = load_flow_from_json( ^^^^^^^^^^^^^^^^^^^^ File "Lib\site-packages\langflow\load\load.py", line 65, in load_flow_from_json graph_data = flow_graph["data"] ~~~~~~~~~~^^^^^^^^ KeyError: 'data'

To resolve the KeyError: 'data' when using the run_flow_from_json function, ensure that the JSON structure you are passing to the function contains the key 'data'. The function expects a dictionary with a 'data' key that contains the necessary information.

Here is an example of how you might structure your JSON to avoid the KeyError:
