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

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?

Hi Turribeach, no it does not.

Added the following error code to the first post:

Response via support back then: "We couldn't find a clear cause, but we suspect the offending environment variables were coming from a stray file that somehow DSS didn't manage to regenerate. But there isn't anything in the logs about it failing, nor incorrect permissions, so we're not clear how it happened. We'll have to keep an eye on it and hope to collect more evidence to narrow down on a possible cause."

I don't fully recall what I did back then to solve it, but it either involved using a different data source or resetting the project.
