exclude_members not working in global section

[kleinski]

Hello Nagvis-Team,

1st up: Thank you for your work, it's highly appreciated!

I have a bug here at least in the regarding the exclusion of services:

Using the docker version of Checkmk 2.2.0p20 the exclusion works fine and excludes the Uptime service on a per host basis, here is the whole config file of the map:

define global {
alias=Default
object_id=0
}

define host {
host_name=localhost
x=370
y=166
object_id=e14771
label_text=[name]
label_show=1
exclude_members=^Uptime$
only_hard_states=1
}

When I use the same exclude config line in the global section...

define global {
alias=Default
object_id=0
exclude_members=^Uptime$
}

... it leads to an error:

Error: (0) explode(): Passing null to parameter #2 ($string) of type string is deprecated
