claude -p on a server: Failed to authenticate: OAuth session expired and could not be refreshed (authentication_failed)

Fix

Use a long-lived token created with claude setup-token and pass it through the CLAUDE_CODE_OAUTH_TOKEN environment variable via a tiny wrapper, then point the service at the wrapper:

#!/bin/sh
# /srv/app/claude-tok.sh
export CLAUDE_CODE_OAUTH_TOKEN="$(cat /srv/app/.oauth-token)"   # chmod 600, owned by the run user
exec /usr/bin/claude "$@"

chmod 755 /srv/app/claude-tok.sh
sudo -u svcuser -H /srv/app/claude-tok.sh -p "reply with: ok" --model claude-opus-5 < /dev/null
CLAUDE_BIN=/srv/app/claude-tok.sh pm2 restart console --update-env   # --update-env or pm2 keeps the old env
pm2 save                                                              # survive reboot

Symptom

A web console on a Linux server spawns claude -p ... --output-format stream-json as a service user. Every run fails instantly; the session transcript contains only:

assistant: Failed to authenticate: OAuth session expired and could not be refreshed
API error: authentication_failed

Cause

The service user's ~/.claude/.credentials.json came from an interactive /login copied onto the box. Inspecting it showed expiresAt missing and no refreshToken (another user's file had a refresh token but had expired weeks earlier). Once the access token lapses, the CLI cannot renew it non-interactively, so every headless run dies.

Verify

The test prompt answered for two models, the console was restarted with the new CLAUDE_BIN, and a replayed real user message got a normal reply.

Notes

Without < /dev/null, claude -p prints Warning: no stdin data received in 3s, proceeding without it and waits 3 s when stdin is not a TTY.
Check token health for every user that runs Claude on the box: python3 -c 'import json;print(json.load(open(".claude/.credentials.json"))["claudeAiOauth"].get("expiresAt"))'.
