An error occurred while loading the map layer

/etc/renderd.conf と landcover-low-zoom という名前の mapnik.xml レイヤーを確認することから始め、次に、PostgreSQL の構文エラーを再現するため、文書化された renderd コマンドを _renderd として再実行します。POW 式の周辺で生成された SQL を比較し、s2o マップレイヤーがエラーなしで読み込まれることを確認します。

I am follwing Switch2OSM link (https://switch2osm.org/serving-tiles/manually-building-a-tile-server-ubuntu-24-04-lts/) for tileserver implementation & I am getting the following error:

The only difference is I am trying to implement it without systemd service that ubuntu offers. Kindly provide me a solution to overcome the above error. Thanks in advance
