"%s" is neither an enabled bundle nor a directory.

Error message

"%s" is neither an enabled bundle nor a directory.

What it means

Thrown by `debug:translation` when the optional `bundle` argument does not resolve to a registered bundle (the kernel's `getBundle()` throws `InvalidArgumentException`) AND the same value treated as a filesystem path has no `translations/` subdirectory. The command tries the bundle registry first, then falls back to treating the argument as a directory path, and only throws when both fail.

Solutions

1. Check `config/bundles.php` to confirm the bundle is registered and note its exact name.
2. If passing a path, ensure it contains a `translations/` subdirectory.
3. Run without the bundle argument to debug application-level translations in the default directory.
4. Use `--all` to scan all registered bundles instead of naming one.

Example fix

// before
php bin/console debug:translation en AcmeDemo

// after (correct bundle name or a real path)
php bin/console debug:translation en AcmeDemoBundle
# or
php bin/console debug:translation en /full/path/with/translations

// Validate the bundle argument before scripting the command.
$bundles = array_map(fn($b) => $b->getName(), $kernel->getBundles());
$isBundle = in_array($arg, $bundles, true);
$isDir = is_dir($arg.'/translations');
if (!$isBundle && !$isDir) {
    // neither bundle nor directory; reject early
}

function bundleOrDirIsValid(\Symfony\Component\HttpKernel\KernelInterface $kernel, string $arg): bool
{
    $names = array_map(fn($b) => $b->getName(), $kernel->getBundles());
    return in_array($arg, $names, true) || is_dir($arg.'/translations');
}

try {
    $exit = $command->run($input, $output);
} catch (\Symfony\Component\Console\Exception\InvalidArgumentException $e) {
    // list bundles or check the directory path
}

When it happens

Trigger: Running `php bin/console debug:translation en SomeBundle` where `SomeBundle` is not registered in the kernel, or `debug:translation en /path/to/something` where `/path/to/something/translations/` does not exist.

Common situations: Bundle name typo, bundle not enabled in `config/bundles.php`, bundle registered under a different alias (extension alias vs bundle class name), or pointing at a directory that lacks the expected `translations/` structure.
