slack bot not answering back. 

I run the docker command docker run -v ./appsettings.json:/app/appsettings.json --restart always ghcr.io/prographers/slack-gpt:latest and everything works fine..... But when I ask a question on slack, I see everything running on the terminal. but I don't get the answer back on slack. what am i missing???? its like it processes the question but doesn't spit out the answer. Hope someone can help!
