AspNetCoreExample in socket mode does not receive events

[tahasi]

I'm new to Slack app development and I'm undoubtably doing something wrong.

I configured the AspNetCoreExample/appsettings.json with my Slack app's tokens and secrets followed by changing the example's call to SlackEndpointConfiguration.UseSocketMode to pass true.

I then set a break point in SlackSocketModeClient.HandleRequest, run the example, switch to the Slack application, navigate to my app's App Home and type a message.

I expected that SlackSocketModeClient.HandleRequest would be called and I'd have an opportunity to learn about the messaging that my app will receive from Slack.

Unfortunately, I'm not seeing any messages coming from Slack.

Is there more that needs to be changed in the example to enable running locally in web-socket mode?

Here's my app's manifest:

display_information:
  name: Aegis App
  description: Your one place incident manager.
  background_color: "#3d4a75"
  long_description: Your one place incident manager with a lot more verbiage to ensure that this description is at least 175 characters which is actually a lot of characters to require for an application's description.
features:
  bot_user:
    display_name: Aegis App
    always_online: true
oauth_config:
  scopes:
    bot:

The app manifest was missing settings.event_subscriptions; hence, not it was not subscribed events.
