MariaDB query running out of memory but failing silently

I'm writing an artisan command.

I've got an SQL query that runs out of memory because it's returning a large amount of data.

I can fix that, the problem is Laravel isn't giving me any PHP errors.

I used Tinkerwell to test the statement it and that gives me a PHP error.:

Symfony\Component\ErrorHandler\Error\FatalError

Allowed memory size of 536870912 bytes exhausted (tried to allocate 4096 bytes)

at vendor/laravel/framework/src/Illuminate/Database/Connection.php:366

But when placed in a command (inside a method), execution apparently just "stops"; with no errors in the CLI or laravel.log.

I have APP_ENV = local and APP_DEBUG = true.

            return DB::table('project_country_pageviews')
                ->select('project', 'date', 'country', 'views')
                ->whereBetween('date', [
                    $period->first()->format(config('app.date_format.default')),
                    $period->last()->format(config('app.date_format.default'))
                ])
                ->get();

it's inside a method. I tried wrapping it in try/catch, but that didn't seem to do anything.

Suggestions?

Environment: PHP 8 on macOS using Homebrew for MariaDB and running Laravel Valet (though this is all CLI stuff).
