Proposed fix: [Click 8.3.0 + old Typer/Click-based CLIs] every command fails with 'TypeError: Secondary flag is not valid for non-boolean flag.' (AppWorld 0.1.3, ScanCode, Open WebUI)
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Upgrade typer to >=0.18.0 (or the CLI to a release that supports Click 8.3); if the CLI itself cannot be upgraded, pin click<8.3.0 (8.2.1 reported working).
Option: Upgrade typer (>=0.18.0) or pin click<8.3.0 [evidence: external_success_report]
Applies when: Any Typer/Click CLI failing at startup with this TypeError
Steps:
1. pip show click typer
2. If typer < 0.18.0: pip install -U 'typer>=0.18.0' (if the app permits)
3. Otherwise: pip install 'click<8.3.0'
4. Re-run '<cli> --help'
Expected: CLI starts normally
