Message bird adapter not working

[KarlynG]

Hi.
I'm trying to use the MessageBird Adapter Sample but I can't get it to send a reply back. I have a Whatsapp Channel configured in message bird and a Webhook also configured. The request to my webhook URL (to the adapter sample) return 200 but there is no reply back in the Whatsapp chat I'm testing with. I have correctly configured the MessageBirdAccessKey, MessageBirdSigningKey and MessageBirdWebhookEndpointUrl in the appsettings.json.

Just want to add that if I use the MessageBird Conversation Api I can send a message to the chat. The issue is when the code reachs the await turnContext.SendActivityAsync(reply); which is suppose to send a message, is not sending anything at all.

Any help?

Edit:
I added this piece of code to test if the application was working as expected with those values and it replies back with the "Test" message. Is there any reason why the default implementation is not working?

client.SendConversationMessage(turnContext.Activity.Conversation.Id, new ConversationMessageSendRequest()
                        {
                            ChannelId = turnContext.Activity.ChannelId,
                            ConversationId = turnContext.Activity.Conversation.Id,
                            Type = ContentType.Text,
                            Content = new Content() { Text = "Test" },
                        });
