Recreate A Missing Notion Entity
Most operations you run from the CLI involve doing some operation on the local store, then mirroring the operation on Notion side. This does not happen atomically and there's a chance the first stage succeeds while the second one fails. This might occur because the network is down or Notion has some issues, or some bug in Jupiter itself.
In any case, fixing such issues is simple. Simply sync like so:
$ jupiter sync
This will catch the missing Notion entity and create it there.
