In CodeBook, I open a notebook and run a cell, and the cell stays at [*] indefinitely. No output is ever produced. The kernel indicator shows "Restarting" and "Waiting", and it never settles into a connected/idle state. This happens with the sample notebooks as well as my own, and on every notebook I try.
It behaves the same whether I open CodeBook from inside Workspace (the CodeBook app) or by going to the CodeBook URL directly.
ENVIRONMENT
Linux, Chromium 150. Workspace Web shows a "BROWSER NOT SUPPORTED" banner in this browser, so please do tell me if CodeBook is only supported on specific browsers and this is the cause - I would rather know that than keep troubleshooting.
QUESTION
Is this a known problem with CodeBook kernels, and what do I need to do to get code execution working again?
