Extracting the error: This issue emerged semi-recently and can be mitigated by pinning to The issue seems to be that in jupyterlab-server 2.22, something changed with how the schema resources are located, and it's no longer correctly finding "share/jupyter/lab/schemas/@jupyter-notebook/notebook-extension/scroll-output.json".
