Hello, I am experiencing an authentication failed error. I have not changed my notebook, and it was working fine a short while ago. Could you please check?

I know I can get the ID by usingprint(f"{slice}")but is there anyway to pass this automatically?slice = fablib.get_slice(SLICENAME,"something to get the ID")Yeah, I think your bastion key expired. They expire every 6 months. Try creating another one and retry.

Hi Paul,
Thanks,
Do you know how to get the slice ID?
slice = fablib.get_slice(SLICENAME,"something to get the ID")
