. Here is a working example:
json
{
"name": "Information Gathering Demo",
"nodes": [
{
"type": "conversation",
"name": "Greeting",
"prompt": "Hey there! Ask users what kind of voice agent they want to build. Be friendly and conversational.",
"isStart": true
}
],
"edges": []
}
This should resolve the API error and create your workflow successfully.
