Unclear It is not clear whether or where Claude Code shows this error to you.
What
Claude Code keeps your past sessions (saved conversations) in a sessions folder. The code that lists them can now report a problem when that folder cannot be read, or when listing the session ids fails with certain errors. Before, it returned an empty list without saying anything.
Why
An empty session list could mean you had no sessions, or that the folder could not be read. This change makes it possible to tell those apart.
