ruby - AWS Codedeploy failed during Install: UnknownError "\xCC" from ASCII-8BIT to UTF-8 -

i have tried troubleshoot unknownerror returned codedeploy agent on amazon linux ec2 instance. push files local git repo on mac s3 bucket, , deploy there ec2 instance.

i have edited /etc/codedeploy-agent/conf/codedeployagent.yml , set :verbose: true on ec2 instance. tried deploy again , open codedeploy-agent.log @ /var/log/aws/codedeploy-agent.

the last lines in log before failing shows agent installs elb scripts provided aws.

i have tried $ grep --color -in -r '\xcc' /my/folder/ returns like

binary file /my/folder/a.png matches

but returned /my/folder/wp-content/plugins/wordpress-seo/admin/class-metabox.php:348:'Ì'

so removed plugin , tried convert filenames ascii utf-8 convmv (it didn't convert anything). without success.

i have updated several gems according couple of stackoverflow threads.

how mitigate error? find error message amazon codedeploy vaugue , hard troubleshoot , i've run out of ideas.

issue looks lang env has not been set when installing / starting codedeploy.

i found if restart codedeploy via cli app deploy without issue.

you can check lang env of codedploy process running

ps auxe |grep codede 

we deploy codedeploy via puppet , have set (environment => 'lang=en_us.utf-8') when running install script.
