HI,
when i send message response content type as ImageResponseCard from lambda to lex like shown below:
"messages": [
{
"contentType": "ImageResponseCard",
"content": "string",
"imageResponseCard": {
"title": "string",
"subtitle": "string",
"imageUrl": "string",
"buttons": [
{
"text": "string",
"value": "string"
}
]
}
}
]
It throws error like :"Invalid Lambda Response: Lambda response did not provide a message and no prompts were configured", and i cant able to send imageResponsecard as a message but when i send plainText as the response it is displaying in lex from lambda
It was working fine before lex update on aug17 after update when we create new bot and invoke the lambda on fulfillment it shows error like this.
