Getting Conversation not found. error when sending message via CloudAdapter

[Hyokune]

Versions

• botbuilder 4.22.3
• Node 20
• Linux / macOS

Describe the bug

When we are sending messages to conversations, we are receiving these errors sporadically

• Conversation not found.
• User blocked the conversation with the bot.

We have confirmed that the conversation exists and that the user has not blocked the conversation but these errors are still being returned.
Additionally we haven't changed any code from our end and have been using the same way to send messages for the past year or so.
Assumed maybe it could be due to rate limiting issues but that doesn't seem to be the case as it throw errors when trying to send the messages individually.

To Reproduce

Steps to reproduce the behavior:

1. Create a CloudAdapter instance using createBotFrameworkAuthenticationFromConfiguration for the bot framework authentication
2. Attempt sending a message via

await cloudAdapter.continueConversationAsync(
  "<microsoftBotId>",
  "<reference>",
  async (context: TurnContext) => {
    await context.sendActivity("Some message here");
  }
);

3. Check error thrown

Expected behavior

Message should be sent successfully to the conversation

I'm guessing this is a Teams bot?

Yes this is a Teams bot

"User blocked the conversation with the bot." is not controlled by anything in Bot Framework. If this is still an issue, I would start with Teams to resolve.
