claude-code - 💡(How to fix) Fix [BUG] All paste methods fail silently during OAuth prompt only [1 comments, 2 participants]

Preflight Checklist

What's Wrong?

The Problem

• Symptom: Pasting (both Ctrl+V, Right-Click, Shift+Insert, and Ctrl+Shift+V altered keybindings) fails exclusively during the claude CLI authentication prompt.
• Context: Windows Terminal running Fedora 43 in WSL.
• Observation: Pasting works perfectly in the standard shell and other applications within the same terminal session; it only "dies" when the claude auth prompt is active.

Theories Explored

1. Terminal Mapping Conflict: Investigated if Windows Terminal was failing to intercept Ctrl+V or if Paste was double-bound to another action.
2. Input "Raw Mode" Interference: Suspected the claude tool enters a "Raw" or "Masked" input state for security, which can cause some CLI tools to ignore "burst" inputs (like a paste) in favor of individual keypresses.
3. Bracketed Paste Protocol: Considered that the "Bracketed Paste" mode (which wraps pasted text in escape codes like \e[200~) was confusing the auth prompt, causing it to reject the input.
4. Clipboard Sync Lag: Looked into WSLg/Wayland clipboard desynchronization between the Windows host and the Linux guest.
5. Tool-Specific Regression: Identified a likely bug/regression in specific versions of claude-code (specifically around v2.1.105) that breaks terminal input handling during OAuth flows. When I downgraded to v2.1.104, the paste functionality worked flawlessly.

Attempts & Workarounds Tried

• Settings Toggles: Adjusted Allow OSC 52 and Legacy Input Encoding in Windows Terminal.
• Shortcut Alternatives: Tested Ctrl+Shift+V, Shift+Insert, and Right-Click (all failed in the auth prompt).
• Protocol Reset: Executed printf "\e[?2004l" to manually disable Bracketed Paste Mode.
• Command Palette: Attempted to force a paste from the Terminal's internal command menu (Ctrl+Shift+P -> Paste).

Conclusion / Areas for Further Investigation

The fact this works in the previous stable release, it tells me there was some form of a regression introduced in .105.

What Should Happen?

The paste functionality should work.

Steps to Reproduce

Assumptions: Windows 11 and WSL is already installed

1. Install Fedora 43, patch it fully, and ensure npm is installed
