What's Wrong?

I ran this:

claude --teleport session_011CUNPVCEo76Q5UFhpdUSfC

And got this:

Error: Failed to fetch session from Sessions API: Request failed with status code 401

Then later on using Claude I got this error which helped me understand what had happened:

  ⎿ API Error: 401 {"type":"error","error":{"type":"authentication_error","message":"OAuth token has expired. Please obtain a
     new token or refresh your existing token."},"request_id":"req_011CUNXzmfi3wLr55CJjTCRH"} ·
Please run /login

After I had done that my claude --teleport command worked correctly.

What Should Happen?

If claude --teleport fails with a 401 error it should output a message like this:

OAuth token has expired. Please obtain a new token using /login

See above.

Steps to Reproduce

Attempt to run claude --teleport X after your OAuth token has expired.
