External foreman-proxy installation

Problem:

Having a foreman-server/foreman-proxy in one server I’m trying to install foreman-proxy in a separated freshly installed server following the doc in Foreman :: Manual (section 3.2.3):

foreman-installer \
  --no-enable-foreman \
  --no-enable-foreman-puppet \
  --no-enable-foreman-cli \
  --no-enable-foreman-cli-puppet \
  --no-enable-puppet \
  --enable-foreman-proxy \
  --foreman-proxy-foreman-base-url=https://foreman-server.com \
  --foreman-proxy-trusted-hosts=foreman-server.com \
  --foreman-proxy-oauth-consumer-key=<key here> \
  --foreman-proxy-oauth-consumer-secret=<secret here>

One of the problems is foreman-installer doesn’t recognized the following option:

ERROR: Unrecognised option '--no-enable-foreman-puppet'

Executing the installer without that option it raised the following errors:

2022-01-24 12:18:20 [ERROR ] [configure] Evaluation Error: Error while evaluating a Resource Statement, Foreman::Plugin[puppet]:                                                                                                               
2022-01-24 12:18:20 [ERROR ] [configure] parameter 'version' expects a String value, got Undef

Expected outcome:

foreman-installer installs foreman-proxy without any error.
