Response from chatbot never shown

I followed your example and added my API key and assistent id inside the .env file.

When choosing the "All" page i can see the files i manually uploaded to the assistent, so i believe the API key and assistent id has been setup correctly.

But when i try to send a message, i never get a response back. Are you sure this template is working? 

My assistent is using gpt-4o as model
