Amazon Linux 2でsystemdサービスが失敗するのはなぜですか?

Amazon Linux 2でsystemdサービスが失敗するのはなぜですか?

Amazon Linux 2を実行しているAWS EC2インスタンスからNode.jsアプリケーションをレプリケートしました。

server.jsプロジェクトファイルを正常に実行できます。

[ec2-user@ip-*********** portfolio_v3]$ nvm use 16
Now using node v16.19.1

[ec2-user@ip-*********** portfolio_v3]$ MAIL_JET_API_KEY_PRIVATE="..." NYT_API_KEY="..." node server.js
...

アプリケーションが常に実行され、次のようにシステムサービスを作成しようとしています。この練習

私は以下を持っています/etc/systemd/system/portfolio-v3.service

[Unit]
Description=portfolio-v3
After=multi-user.target

[Service]
Environment=MJ_API_KEY_PRIVATE=1234567890
Environment=NYT_API_KEY=1234567890
ExecStart=/home/.nvm/versions/node/v16.19.1/bin/node /home/ec2-user/portfolio-v3/server.js
Restart=always
RestartSec=10
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=portfolio-v3
User=ec2-user

[Install]
WantedBy=multi-user.target

次のコマンドはすべて異なる順序で実行されました。

sudo chmod 644 /etc/systemd/system/portfolio-v3.service
sudo systemctl daemon-reload
sudo systemctl enable portfolio-v3.service
sudo systemctl start portfolio-v3.service

ただし、引き続き次の内容が表示されます。

$ sudo systemctl status portfolio-v3.service

どんなアイデアがありますか?またグーグルをしましたが、code=exited, status=203/EXEC結果はあちこちにありました。

ありがとうございます:)
