gettting another cron message: Plugin hook before_send_message called with the params: $VAR1

[udgithub]

Hi Kyle,

you just eliminated the error from my previous issue:
Argument "{VERSION}" isn't numeric in int at /usr/share/koha/lib/Koha/Plugins/Base.pm line 329.

And as you recommend I installed the new version 2.2.2 of the plugin.
Now our cron jobs create the following messages all the time:

Plugin hook before_send_message called with the params: $VAR1 = {
'letter_code' => undef,
'verbose' => 0,
'type' => '',
'limit' => undef
};

Could you explain why this happens?

And could you please tell me why we got the {VERSION} warning all the time?
Could you fix it by adding this line
plugin-module: "Koha/Plugin/Com/ByWaterSolutions/KitchenSink.pm"
to main.yml ?

Thanks,

UD
