gemini-cli - 💡(How to fix) Fix Bug Report: Unhandled Promise Rejection on OAuth Callback Timeout [1 participants]

What happened?

The CLI crashes with a critical unhandled promise rejection during the authentication flow. This occurs when the OAuth callback exceeds the internal timeout limit, likely due to a slow network connection or a delay in the user completing the browser-based authentication.

Error Details Error Type: CRITICAL: Unhandled Promise Rejection!

Reason: Error: OAuth callback timeout

Module: @google/gemini-cli

Location: bundle/chunk-6DSAZLFF.js:324841:29

Stacktrace

Error: OAuth callback timeout
    at Timeout._onTimeout (file:///C:/Users/USER/AppData/Roaming/npm/node_modules/@google/gemini-cli/bundle/chunk-6DSAZLFF.js:324841:29)
    at listOnTimeout (node:internal/timers:605:17)
    at process.processTimers (node:internal/timers:541:7)

Steps to Reproduce Run a command requiring authentication (e.g., gemini login or any query if unauthenticated).

Wait for the browser to open for OAuth.

Allow the timeout period to elapse without completing the sign-in, or experience a significant network delay during the callback.
