Issue with Dialog flow

[dark_smoke]

Hi,

I'm trying to create a simple chat bot using dialog flow, but when the below/any custom payload, I'm getting the response bot as [empty response]. Am I missing something or I have to add something the the snippet.

{
"richContent": [
[
{
"type": "info",
"title": "java error",
"text": [
"1. Kindly open the preference.",
"2. Go to Intelligence.",
"3. Kindly keep the preferences as interactor.",
"4. Save it"
]
}
]
]
}
