symfony/translation · error · InvalidArgumentException

" " is neither an enabled bundle nor a directory.

Error message

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

What it means

Validation guard in TranslationDebugCommand::execute(): the value passed to the 'bundle' argument is neither the name of a bundle registered in the kernel nor an existing filesystem directory, so no translation/code paths can be derived from it. Fires when the argument contains a typo, a bundle that is not enabled, or a path that does not exist.

Solutions

1. Pass the exact bundle name as registered in the kernel, e.g. 'AppBundle' or the full class name 'App\AppBundle'.
2. Pass an existing directory that contains the translations/views layout instead of a bundle name.
3. Run `php bin/console debug:router`-style discovery: use `php bin/console debug:container --parameter=kernel.bundles` (or list bundles via debug:config) to confirm the bundle is enabled.
