@timothycarambat commented on GitHub (Apr 10, 2026):

This is expected behavior, not a bug. The navigator.clipboard API is only available in secure contexts, which means:

  • HTTPS connections
  • localhost / 127.0.0.1

If you're hosting AnythingLLM on a remote server over plain HTTP, the browser will not expose the Clipboard API at all (navigator.clipboard is undefined), which causes this error.

Solutions:

  • Use HTTPS - Set up a reverse proxy (nginx, Caddy, Traefik) with SSL/TLS in front of your AnythingLLM instance
  • Use localhost - If accessing from the same machine, use localhost instead of the IP/hostname
  • Manual copy - Select the code snippet text and copy it manually (Ctrl+C / Cmd+C)

This is a browser security restriction, not something AnythingLLM can work around. Modern browsers intentionally block clipboard access on insecure origins to prevent malicious sites from reading or writing clipboard data without user knowledge.
