Expected Behavior

Using Cmd+Esc from within the JetBrains IDE works as an alternative to connect Claude Code with IDE integration.

same problem on Linux
same problem too
same problem
I also found that clicking the Claude Code icon in VS Code showed the command 'claude-vscode.editor.openLast' not found. Reinstalling the Claude Code extension fixed it. After restarting VS Code, the icon worked normally again, and /ide in the Claude Code terminal also worked (I also manually updated the Claude Code in the terminal)

Same problem with VS Code on Mac
Same issue on ubuntu with node v22
Same issue with VSCode on Ubuntu 22.04. Solved after connecting to IDE first inside vscode's integrated terminal.
@millaker thanks - this fixed it! too bad they don't allow contributions, this doesn't seem like a super hard patch
This is still happening when using
/idefrom the terminal outside of the IDE. Happening in Windows with VSCode.This issue has been automatically locked since it was closed and has not had any activity for 7 days. If you're experiencing a similar issue, please file a new issue and reference this one if it's relevant.
