Code Example

var connector = new ConnectorClient(new Uri(activity.ServiceUrl));
Activity typingReply = activity.CreateReply();
typingReply.Type = ActivityTypes.Typing;

//exception will be thrown here
await connector.Conversations.ReplyToActivityAsync(typingReply);

Actual Results

WebChat is working fine
Facebook connection works fine and the bot code will be triggered.
part of the input message:
....
"serviceUrl":"https://facebook.botframework.com","channelId":"facebook","from":{"id":"14148xxxxxxxxxx","name":"Martin xxxxx"},"conversation":
.....

Strange thing is that all works fine for the last months.
But today I got this issue.

Did facebook changed anything?

Any solutions or ideas?

quick update:

I updated microsoft.bot.builder.azure from "3.2.5" to "3.15.2.2".
Still WebChat and DirectLine are working fine.

From Facebook I got the error message:

My fault:
Somehow my page access token was wrong. The error message was jsut confusing. After going into the step-by-step doc i was able to fix it.

Same has just happened to my bot in Telegram, and your answer was helpful.

I went to @BotFather in Telegram and invoked the /revoke command to change the token to access HTTP API.
Then I went to my Functions bot in the Azure Portal, and on Channels blade clicked on "Edit" on my Telegram bot. I pasted the new Access token, saved, and it works again!

Looks like the token somehow expired. I created my bot 355 days ago (Dec 14, 2017), and haven't changed the token since then.
