Description of problem:

I was trying to enable rsyslog in overcloud deployment.
I included in overcloud deploy command  /usr/share/openstack-tripleo-heat-templates/environments/logging-environment-rsyslog.yaml along with custom yaml file with the following content:

parameter_defaults:
    RsyslogElasticsearchSetting:
        uid: "elastic"
        pwd: "dcS71OJc5j42748xTr61mdcW"
        skipverifyhost: "on"
        allowunsignedcerts: "on"
        server: "https://elastic-service-telemetry.apps.leonidcluster.lab.upshift.rdu2.redhat.com"
        serverport: 443

Overcloud deployment failed with the following error:

 Evaluation Error: Error while evaluating a Function Call, epp(): Invalid EPP: Syntax error at end of input (file: /etc/puppet/modules/rsyslog/templates/action.epp) (file: /etc/puppet/modules/rsyslog/manifests/component/action.pp, line: 13, column: 14) (file: /etc/puppet/modules/rsyslog/manifests/config/actions.pp, line: 3) on node ctrl-0-16-2.redhat.local", "+ rc=1", "+ '[' False = false ']'", "+ set -e", "+ '[' 1 -ne 2 -a 1 -ne 0 ']'", "+ exit 1", " attempt(s): 3", "2022-05-02 19:35:25,047 WARNING: 237810 -- Retrying running container: rsyslog", "2022-05-02 19:35:25,047 ERROR: 237810 -- Failed running container for rsyslog", "2022-05-02 19:35:25,047 INFO: 237810 -- Finished processing puppet configs for rsyslog", "2022-05-02 19:35:25,048 ERROR: 237787 -- ERROR configuring rsyslog"]}
