Understanding the Issue with Teams Bot Adaptive Card Action.Submit

If you're working with Microsoft Teams Bot and encountering a perplexing issue where the Action.Submit for the adaptive card returns undefined in a Teams conversation, but functions perfectly in the Bot Emulator, you're not alone. Many developers face this challenge, particularly when transitioning code between development and production environments. In this guide, we will delve into the nuances of this problem and explore a practical solution to ensure your bot performs seamlessly across different channels.

The Challenge

The fundamental issue arises from the distinction in how the Bot Emulator and Microsoft Teams handle adaptive card submissions. While the emulator facilitates a straightforward Action.Submit, Teams requires a specific configuration using an msteams object. This discrepancy can lead to unexpected undefined values, creating confusion during development.

Solution Overview

To effectively solve this issue, we need to adjust the Action.Submit structure in your adaptive card configuration. Here’s how you can do it:

Step 1: Update Action.Submit Structure

The first step is to redefine your Action.Submit action to include the necessary msteams object. Below is the typical structure you might start with:

For Microsoft Teams, modify it to:

Step 2: Handling Cross-Channel Compatibility

While this modification will work in Microsoft Teams, it will not function in the Bot Emulator or any non-Teams channels. To maintain a single card definition that works across platforms, you can implement a check in your message handler.

Example Implementation

You can use the following code to conditionally create the appropriate card based on the channel:

Benefits of Using a Card Helper

Clean Code: Using a helper function to generate your cards can keep your code organized and manageable.

Improved Experience: By maintaining separate versions of your cards, you ensure a consistent user experience across varying environments.

Summary

In conclusion, the issue of receiving an undefined response from an adaptive card's Action.Submit in Microsoft Teams—while it works perfectly in the Bot Emulator—can be resolved with a few modifications to your adaptive card payload. By incorporating the required msteams object and conditionally handling channel-specific aspects, you can create a reliable bot that delivers a smooth user experience, regardless of the platform.

If you implement these changes and follow best practices for cross-channel compatibility, you can significantly improve the functionality of your Microsoft Teams Bot. Happy coding!
