[Lava-users] Problem while testing a new device type template

I was trying to follow the section testing new device template here :

https://validation.linaro.org/static/docs/v2/development-intro.html#developi...

but I am getting the error :

root@master1:/# lava-server manage device-dictionary Unknown command: 'device-dictionary'. Did you mean device-tags? Type 'lava-server help' for usage.

Some versions information : master1:/#lava-server manage version 2.2.28

lab-slave-0:/# lavacli system version 2023.01

Is the documentation outdated, or am I trying to execute the command in the wrong place ? Also what is the best way to debug and check the errors in a new device template ?

Thanks in advance. G.Emad
