Rocket.chat.ansible: "AnsibleUndefinedVariable: 'dict object' has no attribute 'iteritems'" reploying service file

[nickbroon]

Deploying to CentOS 7:

TASK [RocketChat.Server : Deploy the Rocket.Chat service file]
fatal: [rocketchat.mydomain.com]: FAILED! => {
    "changed": false,
    "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute 'iteritems'"
}

Any suggestion to the cause/fix?

[nickbroon]

Does this relate to #74 in some way?

The 'Deploy the Rocket.Chat service file' task using rocketchat.service.j2:

{% for variable, value in rocket_chat_service_environment.iteritems() %}
Environment={{ variable }}={{ value }}
{% endfor -%}

[nickbroon]

Changing it to use rocket_chat_service_environment.items() seemed to fix the problem.

This appears to be an issue with iteritem() being removed in Python 3.

I also get this error and I my ansible version runs in Python 3 on MacOS, installed via homebrew:

$ ansible --version

Super valuable, I just searched this error and I am not using rocketchat or homebrew but am using pyenv along with virtualenvironment and had the version set to 2.7.x but no matter what I did with pyenv the virtualenvironment kept using system default. End solution was to use pyenv-virtualenvironment.
