overrideConfig for specific node

[Stockotaco]

Hi there,

This image shows my chat prompt template node.

The entire flow

I'm trying to override the systemMessagePrompt within the chatPromptTemplate_0 node only, but it appears that if you specify the individual node, it doesn't work.

{
    "question": "Hey, how are you?",
    "overrideConfig": {
        "chatPromptTemplate_0": {
            "promptValues": {
                "transcript": "Hi thanks for joining the call, bob"
            }
        }
    }
}

This seems to work:

{
    "question": "Hey, how are you?",
    "overrideConfig": {
        "promptValues": {
            "transcript": "Hi thanks for joining the call, bob"
        }
    }
}
