No url printed in "Local development"

[Robin-Aschan]

I am following the steps in "Local development" and I notice that no URL is printed when running the back-end URL. What could be the problem?

This is the prompt after running "python3 app.py --port 8000 --model_version mini"
...

x@x:~/git_environment/dalle-playground/backend$ python3 app.py --port 8000 --model_version mini
