我有一个通过服务文件运行的go版本。该服务文件具有以下内容：
[Unit]
Description=testApp
[Service]
Type=simple
Restart=always
RestartSec=5
WorkingDirectory= /home/user
ExecStart=/home/user/testApp
PermissionsStartOnly=true
ExecStartPre=/bin/mkdir -p /var/log/testApp
ExecStartPre=/bin/chown syslog:adm /var/log/testApp
ExecStartPre=/bin/chmod 755 /var/log/testApp
ExecStartPre=/bin/kill -l SIGKILL
ExecStartPost=/bin/bash -c 'curl "IP:PORT/API-URL"'
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=testApp
[Install]
WantedBy=multi-user.target
从上述服务中，我想在启动该服务之前终止所有正在运行的进程。为此，我已经使用
ExecStartPre=/bin/kill -l SIGKILL
终止所有进程后，我希望启动服务，并且在启动服务后应执行api。
现在，每当我重新启动服务时，都会出现以下错误：

任何人都可以解释一下这里发生了什么。我无法得到问题及其解决方案。
谢谢！
