syntax error for sysctl_multi LWRP use

[donnielee]

When I created a parameter.rb under recipes directory and uploaded to the Chef automate, knife displayed below syntax error message. Would you help me what did I wrong?

#cat ~/sysctl/recipes/parameter.rb
include_recipe 'sysctl::default'
sysctl_multi 'ip config' do
instructions {
'net.ipv4.ip_forward' => '1',
'net.ipv6.conf.all.forwarding' => '1',
'net.ipv4.tcp_syncookies' => '1'}
end

I made it with my colleague Jaebok Park's help.

Just include () like below.
#cat ~/sysctl/recipes/parameter.rb
include_recipe 'sysctl::default'
sysctl_multi 'ip config' do
instructions ({
'net.ipv4.ip_forward' => '1',
'net.ipv6.conf.all.forwarding' => '1',
'net.ipv4.tcp_syncookies' => '1'})
end
