Hi @Ankit Patel
As forum moderators, we have some limitations in our test environment and are therefore unable to reproduce your issue. Additionally, there isn’t enough detail provided about your implementation (for example, how the task module is invoked, the task/fetch response payload, or the dialog URL).
From the error message in your screenshot " Unable to reach app. Please try again" when opening task module page in dialog, I found some related discussions that may help:
- "Unable to reach app. Please try again." Error on Message Extension - Microsoft Q&A.
- Task Module shows popup but Adaptive Card does not render using M365 Agent SDK (Python) - Microsoft…
It may also help to review the official sample for guidance: Microsoft-Teams-Samples/samples/bot-task-module/csharp at main · OfficeDev/Microsoft-Teams-Samples …
I hope this points you in the right direction.
