Ansible Tower problems copying .yml config file

Question

Working in Ansible Tower, I am trying to update the codedeployagent.yml file on a server by copying a new version located in a github repo sub-folder called 'files'. However when I run the template in Ansible Tower, I get the following error (below):

ERROR! Syntax Error while loading YAML.
  mapping values are not allowed in this context
The error appears to be in '/tmp/awx/project/files/codedeployagent.yml': line 2, column 14, but may be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
--
:log_aws_wire: false
             ^ here

It's like Ansible Tower is treating the codedeployagent.yml file as an ansible file when I don't want it to do that, I just want to copy the file. Could it be because the config file is a .yml format, do I need to change that in the source repo? This is my ansible playbook (below). Any suggestions appreciated, thanks.
