UpdateActivity throws 400 "Unknown activity type" - botframework

Question

I do have a Bot that is reachable via MS Teams. The bot sends an Adaptive Card with some Text and a submit-action. When the user clicks on this submit-action, I want to proceed the input and then update the prior sent Adaptive card via calling context.updateActivity. According to documentation, I can use activity.Id = turnContext.Activity.ReplyToId; to specify the message I want to update. But the call of context.updateActivity results in a 400 HTTP error, the message is "Unknown activity type".
Some investigation:
This error occurs when I want to send another Adaptive Card and when I want to send plain text
I verified, that the id of sendActivity is the same as turnContext.Activity.ReplyToId
Any idea?
Here is my code:
Adaptive Card
{
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"type": "AdaptiveCard",
"version": "1.0",
"body": [
{
"type": "TextBlock",
"text": "Some text",
"wrap": true
},
{
"type": "Input.ChoiceSet",
"id": "Feedback",
"value": "",
"style": "compact",
"placeholder": "Wie hilfreich war diese Antwort?",
"choices": [
{
"title": "⭐",
"value": "1"
},
{
"title": "⭐⭐",
"value": "2"
},
{
"title": "⭐⭐⭐",
"value": "3"
},
{
"title": "⭐⭐⭐⭐",
"value": "4"
},
{
"title": "⭐⭐⭐⭐⭐",
"value": "5"
}
]
}
],
"actions": [
{
"title": "Feedback absenden",
"type": "Action.Submit"
}
]
}
Sending the message:
private handleMessage = async (context: TurnContext, next: () => Promise<void>): Promise<void> => {
const adaptiveCard = AdaptiveCardFactory.createAdaptiveCardFromTemplateAndData(AnswerWithFeedbackCard);
const result = await context.sendActivity({ attachments: [adaptiveCard] });
console.error("send msg with id " + result?.id);
}
code to update the message:
private handleMessage = async (context: TurnContext, next: () => Promise<void>): Promise<void> => {
console.error("received msg with id " + context.activity.replyToId);
if (context.activity.value && !context.activity.text) {
const updatedCard = CardFactory.adaptiveCard(this.botConfig.updatedCard);
await context.updateActivity({ text: "updated :)", id: context.activity.replyToId});
//or
await context.updateActivity({ attachments: [updatedCard], id: context.activity.replyToId});
}
}

Got it!
const att = AdaptiveCardFactory.createAdaptiveCardFromTemplateAndData(AnswerWithAnsweredFeedbackCard, {
answer: "Mir geht's super, danke der Nachfrage!",
starsCount: context.activity.value.Feedback
});
const id = await context.updateActivity( { attachments: [ att ], id: context.activity.replyToId} );
This does not work, but this does:
const att = AdaptiveCardFactory.createAdaptiveCardFromTemplateAndData(AnswerWithAnsweredFeedbackCard, {
answer: "Mir geht's super, danke der Nachfrage!",
starsCount: context.activity.value.Feedback
});
const msg = MessageFactory.attachment( att )
msg.id = context.activity.replyToId;
const id = await context.updateActivity( msg )
So, you need to save the save the sent msg in a variable and set the id of this variable instead of using the "inplace"-implementation of updateActivity
