Bot Framework Test connection to your bot fails with status code Forbidden

Question

My bot works receives and sends messages fine in Slack, Skype and emulator.

However when I click the blue Test button in the bot portal (https://dev.botframework.com/) it gives me the error message "Authorization for Microsoft App ID my_id_is_replacedhere failed with status code Forbidden"

Full error is below.

I also get the same error when I send a scheduled message to Slack using endpoint https://slack.botframework.com/ and the Conversations.SendToConversation() method. This used to work and the Test button used to succeed.

Why am I getting this message? Is there a NuGet pkg update that broke it? I went through the troubleshooting guide, but everything else seem to work.

Thank you

Answer 1

I figured out what caused the error. Apparently the Test button in the bot portal sends a "Ping" message to the bot. In my MessagesController code I was trying to reply to every message with something like this:

                        ConnectorClient connector = new ConnectorClient(new Uri(Act.ServiceUrl), appcred);
                        Activity reply = Act.CreateReply(replymsg);
                        connector.Conversations.ReplyToActivity(reply);

However - when I do this for the Ping type of Activity (Activity.Type=ActivityTypes.Ping), then I get the above error. When I just ignore the Ping message, then the Test button works.

I still had an issue when I get the same error when sending messages to Slack on a schedule (no incoming message to reply to). I worked around that issue using Slack's WebAPI:

https://slack.com/api/chat.postMessage?token={0}&channel={1}&text={2}&as_user={3}

Try use

MicrosoftAppCredentials.TrustServiceUrl(notify.ServiceUrl, DateTime.MaxValue);

before

connector.Conversations.SendToConversationAsync(...)
