Puppet Error : Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Function Call, Could not find class - puppet

Question

I am testing this out and getting an error on the Puppet agent node
[root#pagent1 ~]# puppet agent -t
Info: Using configured environment 'production'
Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Retrieving locales
Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Function Call, Could not find class ::nginx for pagent1.testcentos7.com (file: /etc/puppetlabs/code/environments/production/manifests/site.pp, line: 3, column: 3) on node pagent1.testcentos7.com
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run
Content of these classes from the Puppet server:
[root#pmaster ~]# cat /etc/puppetlabs/code/environments/production/manifests/site.pp
node pagent1.testcentos7.com {
class { 'nginx': }
}
[root#pmaster ~]# cat /etc/puppetlabs/code/environments/production/modules/nginx/manifests/manifests/init.pp
class nginx {
contain nginx::install
}
[root#pmaster ~]# cat /etc/puppetlabs/code/environments/production/modules/nginx/manifests/install.pp
class nginx::install {
package { 'install_nginx':
name => 'nginx',
ensure => 'present',
}
}
Syntax check shows this error:
[root#pmaster ~]# puppet parser validate /etc/puppetlabs/code/environments/production/modules/nginx/manifests/manifests/init.pp
Error: Could not parse for environment production: Unacceptable location. The name 'nginx' is unacceptable in file '/etc/puppetlabs/code/environments/production/modules/nginx/manifests/manifests/init.pp' (file: /etc/puppetlabs/code/environments/production/modules/nginx/manifests/manifests/init.pp, line: 7, column: 1)
NOTE: Created module 'nginx' and its classes using Puppet Development Kit(PDK).
Is that a bug or something or I made a mistake with the class name?.
Related thread I found is https://groups.google.com/forum/embed/#!topic/puppet-users/nxbwCvWrgMI but would like to have someone simplify this for me

Answer 1

Solved this by moving 'init.pp' to the path /etc/puppetlabs/code/environments/production/modules/nginx/manifests where install class file 'install.pp' exists.
For more clarity, I put both the files 'init.pp' and 'install.pp' in the same location directory /etc/puppetlabs/code/environments/production/modules/nginx/manifests to solve this.
