BotFrameworkAdapter.process_activity_with_identity calls serialize() on dict

[jooste]

Version

4.13.0

Describe the bug

When running, e.g., the fetch task example, an exception is raised when on_teams_messaging_extension_fetch_task is called. The problem is that in bot_framework_adapter.py on line 515, serialize() is called on invoke_response.value.body, which is a python dict.

To Reproduce

Steps to reproduce the behavior:

1. run the above-mentioned example and add to teams
2. Trigger bot's 'create card' message extension
3. A dialog is shown with an error, and an exception is raised in the bot code.

Expected behavior

Expected behavior is that the 'Create Card' example dialog is shown instead of an error. A fix to this error could for instance be to change line 515 in bot_framework_adapter.py to:

return InvokeResponse(
                status=invoke_response.value.status,
                body=invoke_response.value.body   # line 515
