Webhook messages aren't delivered from azure functions
Webhook message delivery failed with error: Microsoft Teams endpoint returned HTTP error 400 with ContextId 01=2
Worked fine since last night. Today morning this error started. Nothing changed overnight. Is this a known bug?

Can you try sending the message using postman once and check you are getting the same error? Also please share the JSON so that we can check from our end as well.{ "type": "message", "summary": "test", "attachments": [ { "contentType": "application/vnd.microsoft.card.adaptive", "contentUrl": null, "themeColor": "0072C6", "summary": "test", "content": { "type": "AdaptiveCard", "body": [ { "type": "TextBlock", "size": "Large", "weight": "Bolder", "text": "test", "wrap": true }, { "type": "TextBlock", "size": "Large", "weight": "Bolder", "text": "messageTitle", "wrap": true }, { "type": "TextBlock", "size": "Medium", "text": "asd", "wrap": true } ], "$schema": "http://adaptivecards.io/schemas/adaptive-card.json", "version": "1.0", "padding": "None", "msteams": { "width": "Full", "entities": [ { "type": "mention", "text": "<at>MAK</at>", "mentioned": { "id": "email address removed for privacy reasons", "name": "name" } } ] } } } ] }- Meghana-MSFT
abdul_kareem_mohamme - We checked this at our end, we made a change to the card to make sure it follows this pattern. It is working fine. - https://learn.microsoft.com/en-us/microsoftteams/platform/task-modules-and-cards/cards/cards-format?tabs=adaptive-md%2Cdesktop%2Cconnector-html#user-mention-in-incoming-webhook-with-adaptive-cards
We need to add "<at>Admin</at>"(Same as text property in entities) in text block of body so that it will show the @mention properly. We also replaced the text in entities block. Below is the final JSON.
{ "type": "message", "summary": "test", "attachments": [ { "contentType": "application/vnd.microsoft.card.adaptive", "contentUrl": null, "themeColor": "0072C6", "summary": "test", "content": { "type": "AdaptiveCard", "body": [ { "type": "TextBlock", "size": "Large", "weight": "Bolder", "text": "test", "wrap": true }, { "type": "TextBlock", "size": "Large", "weight": "Bolder", "text": "messageTitle", "wrap": true }, { "type": "TextBlock", "size": "Medium", "text": "Hi <at>Admin</at>", "wrap": true } ], "$schema": "http://adaptivecards.io/schemas/adaptive-card.json", "version": "1.0", "padding": "None", "msteams": { "width": "Full", "entities": [ { "type": "mention", "text": "<at>Admin</at>", "mentioned": { "id": "admin@M365x17798679.onmicrosoft.com", "name": "Admin" } } ] } } } ] }If you are still facing the issue even after making these changes, could you please share demo credentials where this issue is reproducible. Please share the credentials at microsoftteamsdev@microsoft.com.
