Method return time error

[mushi-nova]

I been trying to run mantablockscreen from the terminal but until I wasn't successful since I'm getting this error which I really don't understand. Here's the error

$mantablockscreen

method return time=1589281587.817201 sender=:1.4 -> destination=:1.36 serial=169 reply_serial=2
   boolean true
method return time=1589281587.821509 sender=:1.4 -> destination=:1.37 serial=170 reply_serial=2
   boolean true
i3lock: unrecognized option '--force-clock'
i3lock: Syntax: i3lock [-v] [-n] [-b] [-d] [-c color] [-o color] [-w color] [-l color] [-u] [-p win|default] [-i image.png] [-t] [-e] [-I timeout] [-f] [--24]
method return time=1589281588.841849 sender=:1.4 -> destination=:1.38 serial=171 reply_serial=2
   boolean true
method return time=1589281588.847968 sender=:1.4 -> destination=:1.39 serial=172 reply_serial=2
   boolean true

Don't really know if this is pointing to something missing or not but I have all the dependencies installed but still I wasn't able to run it any how. I would be glad if anyone can suggest me something.

Default i3lock and i3lock-color have the same binary name so you should uninstall default i3lock before start
