minimal jupyterlab notebook cannot be rebuilt

[MichaelTiemannOSC]

A project I'm working on offers the default minimal notebook via Open Data Hub. When I install extensions that require a JupyterLab re-build I get this error:

PermissionError: [Errno 1] Operation not permitted: '/opt/app-root/share/jupyter/lab/staging/index.js'

It occurs because the rebuild script attempts to do a chmod after copying a file and the 755 permissions for both this file and its containing directory do not permit my notebooks's UID (1000640000) to perform that operation. Here are some more details:

PermissionError: [Errno 1] Operation not permitted: '/opt/app-root/share/jupyter/lab/staging/index.js'

You will need to ask Red Hat. Open Data Hub is their product and they have their own Jupyter notebook images for working with it. This project here is no longer maintained.
