Failed to parse inline template

[jg-development]

Hi,

I am just using the logstashforwarder as described in the example:

class { 'logstashforwarder': }

The result is the following line:
Failed to parse inline template: undefined method `sort' for nil:NilClass at /tmp/vagrant-puppet/modules-5fb4a587328a1815a7de96967c07c0f5/logstashforwarder/manifests/config.pp:117

Can somebody tell me what I am doing wrong?
Puppet Version 3.8.2

Greetings
Jan

The documentation doesn't say, but it appears that you need to pass in at least the "servers" parameter to the class, or you'll get this error. It must be an array:

class { 'logstashforwarder':
  servers => ['logstash.example.com:5000'],
}

[dpash]

There's a couple of issues at play here.

Firstly, the documentation should clearly express that servers is needed.

Secondly, despite there being a validate_array($servers) being in init.pp, passing in a single value doesn't give a warning, but gives a similar template error as shown in the title.

Finally, the parameter should probably accept a single value, and deal with it appropriately.

When I use the following yaml to install software and logstashforwarder it works.

yaml of xldeploy host

logstashforwarder::package_url: 'file:/vagrant/salt/states/puppetmaster/files/logstashforwarder-external-resources/logstash-forwarder-0.4.0-1.x86_64.rpm'
logstashforwarder::servers: ["elkagent.home:5043"]
logstashforwarder::ssl_key: ''
logstashforwarder::ssl_cert: ''
logstashforwarder::ssl_ca: '/etc/pki/tls/certs/logstash-forwarder.crt'
logstashforwarder_config::files:
  'xldeploy':
    'paths': ["/opt/xl-deploy/xl-deploy-server/log/deployit.log"]
    'fields':
      'type': 'xldeploy'

[root@xldeployagent ~]# cat /etc/logstash-forwarder.conf 
{
  "network": {
    "servers": [ "elkagent.home:5043" ],
    "ssl certificate": "",
    "ssl ca": "/etc/pki/tls/certs/logstash-forwarder.crt",
    "ssl key": "",
    "timeout": 15
  },
  "files": [
    {
      "paths": [ "/opt/xl-deploy/xl-deploy-server/log/deployit.log" ],
      "fields": { "type": "xldeploy" }
    }
  ]
}[root@xldeployagent ~]

When I use the following yaml to install software and logstashforwarder on a different machine it also works.

yaml of xlrelease host

logstashforwarder::package_url: 'file:/vagrant/salt/states/puppetmaster/files/logstashforwarder-external-resources/logstash-forwarder-0.4.0-1.x86_64.rpm'
logstashforwarder::servers: ["elkagent.home:5043"]
logstashforwarder::ssl_key: ''
logstashforwarder::ssl_cert: ''
logstashforwarder::ssl_ca: '/etc/pki/tls/certs/logstash-forwarder.crt'
logstashforwarder_config::files:
  'xlrelease':
    'paths': ["/opt/xl-release/xl-release-server/log/xl-release.log"]
    'fields':
      'type': 'xlrelease'

[root@xldeployagent ~]# cat /etc/logstash-forwarder.conf 
{
  "network": {
    "servers": [ "elkagent.home:5043" ],
    "ssl certificate": "",
    "ssl ca": "/etc/pki/tls/certs/logstash-forwarder.crt",
    "ssl key": "",
    "timeout": 15
  },
  "files": [
    {
      "paths": [ "/opt/xl-release/xl-release-server/log/xl-release.log" ],
      "fields": { "type": "xlrelease" }
    }
  ]
}[root@xldeployagent ~]

But when I try to install both of the roles on the same machine (I had to fix the code first according to (#62)
I get the error

[root@xldeployagent opt]# puppet agent -t
Info: Retrieving pluginfacts
Info: Retrieving plugin

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Evaluation Error: Error while evaluating a Function Call, Failed to parse inline template: undefined method `sort' for nil:NilClass at /etc/puppetlabs/code/environments/production/modules/logstashforwarder/manifests/config.pp:114:20 on node xldeployagent.home

[root@xldeployagent opt]# 

Any ideas??
