Connect a bot to Slack Interactions

[anil-mndl]

ABS when configured to "Add and configure interactive messages" as stated in the documentation Connect a bot to Slack doesn't forward interactive messages to the bot service.

Sample information

1. Sample type: samples
2. Sample language: all languages
3. Sample name: n/a

Describe the bug

As per the documentation, Slack interactions initiate an HTTP POST request when users interact with interactive components. The request URL is pointed to https://slack.botframework.com/api/Actions which should forward those requests to the URL mentioned in 'Messaging Endpoint' for the bot. This request forwarding doesn't happen.

To Reproduce

Steps to reproduce the behavior:

1. Create a new 'Azure Bot' in Bot Services in Azure portal
2. Add 'Messenging Endpoint' bot configuration.
3. Add 'Slack' as in the channels - a new Slack app need to be created and credentials properly filled in
4. In the Slack app 'Interactivity & Shortcuts' menu, add 'https://slack.botframework.com/api/Actions' in the Request URL as mentioned in the documentation.
5. Render a simple interactive Slack block card - see attached image for a sample card.
6. Click on the interactive button.

Expected behavior

When a user clicks on the button in the interactive block card, Slack initiates a HTTP POST request which should route to the 'Messenting Endpoint' as setup bot configuration. Apparently, no such message is sent from the Bot Services.
