InvalidConsoleOptionName

Emitted when $this->option('name') references an option that is not defined in the command’s signature.

Why this is a problem

If you request an option that doesn’t exist in your command’s $signature, Laravel will throw a RuntimeException at runtime. This check catches the mismatch during static analysis.

Examples

// Bad — 'verbose-output' is not defined in the signature
class ExportCommand extends Command
{
    protected $signature = 'export {file} {--format=csv}';

    public function handle(): void
    {
        $verbose = $this->option('verbose-output'); // InvalidConsoleOptionName
    }
}

// Good — option name matches the signature
class ExportCommand extends Command
{
    protected $signature = 'export {file} {--format=csv}';

    public function handle(): void
    {
        $format = $this->option('format');
    }
}

How to fix

1. Check the $signature property of your command for the correct option name
2. Either fix the option() call to match the signature, or add the missing option to the signature
