there are pages where people are sent to jupyter notebooks on Data Depot rather than directly on DesignSafe Jupyter Hub -- this is a "new" feature.

all you have to do is replace the base path with:

https://jupyter.designsafe-ci.org/hub/user-redirect/lab/tree/

and then it depends on where it is....
Community/....
NHERI-Published/PRJ-....
etc.
