Exception: Unable to fetch schema for PROJECT.dataset: b'Ticket not given or unrecognized

[ebbingcasa]

Hi there,

I encounter the sudden issue of not being able to load datasets into a Jupyter Notebook. Changing environment/Kernel doesn't help. System reboot doesn't help. Force reloading doesn't help neither. Nothing was changed in the code. Flow still runs, so it runs as a receipt but not when trying to work in the Notebook. Any ideas?

Exception: Unable to fetch schema for PROJECT.dataset: b'Ticket not given or unrecognized. Force reload the notebook.'

Edited: I also observe the following error in case it is related

java.lang.SecurityException: Ticket not given or unrecognized

PS: A similar problem from '22 was never (publicly) addressed when raised.

Does your DSS instance use User Isolation Framework?
