我已经在 Laravel 项目上安装了 Sentry，但无法运行它，每当我运行命令时，php artisan sentry:test结果是：
[Sentry] DSN discovered!
[Sentry] Generating test Event
[Sentry] Sending test Event
[Sentry] There was an error sending the test event.
[Sentry] Please check if your DSN is set properly in your config or `.env` as `SENTRY_LARAVEL_DSN`.
但我已在 .env 文件中添加了 DSN
