systemctl daemon-reload fails with Invalid Number of Arguments

Question

On Amazon Linux 2 on ec2 instance I editted the elastic-agent service and I get an error "Invalid number of arguments"

[ec2-user@ip-172-31-21-92 ~]$ sudo systemctl daemon-reload elastic-agent
Invalid number of arguments.

I have edited my service file to look like this:

[Unit]
Description=Agent manages other beats based on configuration provided.
Documentation=https://www.elastic.co/products/beats/elastic-agent
Wants=network-online.target
After=network-online.target

[Service]

Environment="BEAT_LOG_OPTS="
Environment="BEAT_CONFIG_OPTS=-c /etc/elastic-agent/elastic-agent.yml"
Environment="BEAT_PATH_OPTS=--path.home /usr/share/elastic-agent --path.config /etc/elastic-agent --path.data /var/lib/elastic-agent --path.logs /var/log/elastic-agent"
ExecStart=/usr/share/elastic-agent/bin/elastic-agent --environment systemd $BEAT_LOG_OPTS $BEAT_CONFIG_OPTS $BEAT_PATH_OPTS -v
Restart=always

[Install]
WantedBy=multi-user.target

The only edit I made to the installed file was to add the "-v" flag to the end of ExecStart

Answer 1

No need to add elastic-agent, just run

sudo systemctl daemon-reload
