There was a problem hiding this comment. Windows code path bypasses callback and misses success logging. The Windows implementation uses 🔎 Proposed fix to unify error handling case 'win32':
- // Windows 'start' is a shell builtin, use spawn with shell but pass URL as separate arg
- spawn('cmd', ['/c', 'start', '', url], { shell: false }).on('close', (code) => {
- code === 0 ? resolve() : reject(new Error(`Exit code ${code}`));
- });
+ // Windows 'start' is a shell builtin, requires cmd.exe
+ spawn('cmd', ['/c', 'start', '', url], { shell: false }).on('close', (code) => {
+ callback(code === 0 ? null : new Error(`Exit code ${code}`));
+ });
