Splunk universal forwarder package upgrade via puppet failing

[Gajendrap22]

we have 8.1.4 version of splunk universal splunk forwarder in my solaris 11 machine and I'm trying to upgrade it to 9.2.1 via puppet code . the following code is failing and any idea why?

'Solaris': {
$pkg_name = 'splunkforwarder'
$pkg_location = '/nfs/splunk'
$splunk_filedir_owner = 'splunk'
$splunk_filedir_group = 'splunk'
$splunk_service_name = 'splunkforwarder'

case $facts['operatingsystemmajrelease'] {
'11' : {
$pkg_provider = 'pkg'
$pkg_file = 'splunkforwarder-9.2.1-78803f08aabb-solaris-sparc.p5p'
$install_options = [ 'install -g' , "${pkg_location}${pkg_file}" , "${pkg_name}" ]
}
}
}

I've also tried it locally with the following code

package {'splunkforwarder' :
ensure => latest,
provider => 'pkg',
source => '/nfs/splunk/splunkforwarder-9.2.1-78803f08aabb-solaris-sparc.p5p',
install_options => [ 'install -g' , '/nfs/splunk/splunkforwarder-9.2.1-78803f08aabb-solaris-sparc.p5p' , 'splunkforwarder' ],
}

used following install options too
install_options => [ '-g' , '/nfs/splunk/splunkforwarder-9.2.1-78803f08aabb-solaris-sparc.p5p' , 'splunkforwarder' ],
install_options => [ 'update' , '/nfs/splunk/splunkforwarder-9.2.1-78803f08aabb-solaris-sparc.p5p' , 'splunkforwarder' ],
