Teams Bot error AADSTS700016

Hello!

I am creating a bot using Node.js on VSCode, I also used ngrok. It receives the messages since on the ngrok terminal I get this when I send a message to the bot on Teams:

13:34:00.020 CEST POST /api/messages 200 OK

I have the API permissions granted and all the other requested requirements

but the bot does not respond, and on the VSCode terminal I got this error:
