conversation not found

Shraddha Kudalkar 0

Hi there,

We have an application that sends reminders to users and channels on Microsoft Teams.

While sending reminders, we occasionally encounter an error: {"error":{"code":"ConversationNotFound","message":"Conversation not found."}}. This issue appears to be random; in some cases, messages are successfully delivered to the same channel or user, while in others, they are not.

We would appreciate your assistance in understanding the cause of this error, as all messages are sent consistently from our end.

Thank you for your help!

Steps to reproduce the issue:

Fetch token required to send messages/reminders (replace your app id and secret below): Endpoint: https://login.microsoftonline.com/botframework.com/oauth2/v2.0/token Headers:
Content-type : application/x-www-form-urlencoded
Host: login.microsoftonline.com Body: "grant_type=client_credentials&client_id=<app_id>&client_secret=<app_secret>&scope=https%3A%2F%2Fapi.botframework.com%2F.default"

Send Message to user/channel: Required details for user:- A service_url and conversation_id (the unique id of conversation between bot and user) Required details for channel:- A service_url and conversation_id (this is the channel id of a team) Add the above details in the following api: Endpoint: "service_url/v3/conversations/conversation_id/activities" headers: Content-Type: application/json Authorization: Bearer <token_fetched_in_step_1> http method: POST body: { "type": "AdaptiveCard", "body": [ { "type": "TextBlock", "size": "Medium", "weight": "Bolder", "text": "Hi, This is a test message." } ], "$schema": "[http://adaptivecards.io/schemas/adaptive-card.json"], "version": "1.6" }

These are the steps to reproduce the error "Conversation not found". Please note that this occurs randomly for some users/channels and not for all. If you need any specific details (e.g., app_id, app_secret, conversation_id), please specify a preferred method of contact (like email) for sharing sensitive information securely.

@Shraddha Kudalkar - We have tested this but at our end its working fine.
The error message {"error":{"code":"ConversationNotFound","message":"Conversation not found."}} indicates that the conversation ID used to send the message is not found in some cases.
Conversation IDs may expire or become invalid over time. Could you please verify that you are using the most recent conversation ID for each user or channel?
The error might occur if the user or channel is temporarily unavailable. Check if the user or channel is active and available when sending the reminder?

@Nivedipa-MSFT
We retrieved the latest conversation ID for the user, and it matches the ID we’re using to send messages. This issue appears to occur only in a few specific cases.

Could you please provide an email address where we can send more details about the error message? That would be greatly appreciated.

@Shraddha Kudalkar - You have to add the logic for when user gets conversation not found error then you need to create conversation first for this.
Sometimes the conversation might expire during interaction, especially if you’re dealing with a long-running bot. In such cases, use a retry mechanism to attempt a new conversation if “conversation not found” is encountered.
