      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’m assuming this has something to do with the bastion key, which has went missing from my portal.

          How can I get the slice ID?
          I know I can get the ID by using print(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")

                If you have the slice you can call:

                slice_id = slice.get_slice_id()

                In your example, you could do something like:

                slice_id = fablib.get_slice(SLICENAME).get_slice_id()
