2 issues with Puppet and checkcommand

Hi,
I’ve found 2 issues while using puppet to set the “checkcommand”. One is related to the behavior of the puppet module itself and the other is (presumably) with the checkconfig itself.
Description: I’m trying to set multiple filesystem exclusions for the check_disk plugin.

FIRST ISSUE

icinga2::object::checkcommand { ‘main-disk’:
import => [‘plugin-check-command’,],
command => [‘PluginDir + /check_disk’,],
arguments => {
‘-x’ => ‘/dev/sda/’,
‘–exclude-type’ => ‘overlay’,
‘–exclude-type’ => ‘tmpfs’,
},

@@ -27,6 +27,6 @@
command = [ PluginDir + "/check_disk", ]
arguments = {
"-x" = "/dev/sda/"
- "--exclude-type" = "overlay"
+ "--exclude-type" = "tmpfs"
}
}
I’ve made many different attempts but it looks to me that it accepts only unique arguments despite the --exclude-type can be specified multiple times (I’ve tried on the command line directly and it works well (shown below).

SECOND ISSUE
When I try to apply the change directly on the Icinga2 checkcommand file it doesn’t fail but it is not behaving as expected. In fact looks like only one exclusion parameter would work as I keep getting related alerts which are not supposed to show up.
object CheckCommand "main-disk" {
import "plugin-check-command"

command = [ PluginDir + "/check_disk", ]
arguments = {
"-x" = "/dev/sda/"
"--exclude-type" = "overlay"
"--exclude-type" = "tmpfs"
}
}

The command on the shell works well:
(without exclusions)

# ./check_disk -x /dev/sda1

Am I missing something?
Thanks in advance.
