Research direction

Start by reproducing the issue with Chrome on macOS, a remote Ubuntu 24.04 code-server instance, and the Claude Code extension from Open VSIX. Compare the Claude Code attachment flow with the Copilot button, then determine which side owns the file selection behavior. Done means “Upload from computer” selects files from the remote machine rather than the local machine.

Logs

Are you accessing code-server over a secure context?
  • I am using a secure context.
Notes

So, I'm not even sure which side is this relevant to. But this is very bizarre, and the equivalent button in Copilot works the correct way by allowing to choose remote files.

Mainly writing here to leave a record and start the discussion if others have had this issue as well.

Thanks
