Auto redirect to jupyterhub directory

I had made a image FROM mininotebook:python3.8.8 and upgrade some jupyter software
and it can successfully start , but it auto redirect to a dir named jupyterhub which I did not config, How can i do to fix it ?

We’ll need more information to help, see

For example, you’ve tagged this topic as JupyterHub but you’ve only shown us a tiny bit of your JupyterLab/notebook Dockerfile. Are you using JupyterHub, or running the container on its own? What arguments are you passing to it?

Ideally we need enough information to produce your problem from scratch, which includes any config.
