Why does the Invalid argument in journalctl -f cause the service not to start?

Question

linux

journalctl -f Swears that:

Failed to add dependency on redis-server, ignoring: Invalid argument

Here is the service I'm running. There is a launch after redis-server.

[Unit]
Description=Queue worker
After=nginx.service
After=httpd.service
After=redis-server
After=mysql.service
.......

But redis-server itself
# systemctl status redis-server

redis-server.service - LSB: redis-server - Persistent key-value db
   Loaded: loaded (/etc/rc.d/init.d/redis-server; bad; vendor preset: disabled)
   Active: active (running) since Wed 2017-04-19 16:21:23 MSK; 41min ago
     Docs: man:systemd-sysv-generator(8)
