it is installed

you wouldn't be able to get to that web page if it wasn't

Puppet agent is not installed on the agent node or else it would not say puppet command not recognized

I guess I can manually run the installation

sigh

I am failing here, sorry can't explain it better

you need to do it on the server

server is Linux

it can't be Windows

This command will not be recognized on the agent node until puppet agent is setup on the node. I'm confused how do you want me to setup the agent on a windows node

I am not

I am telling you to run puppet on server

/opt/puppetlabs/bin/puppet agent -t

On puppetserver? (Master!)

yes

Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Resource Statement, Evaluation Error: Unknown function: 'is_function_available'. (file: /etc/puppetlabs/code/environments/production/modules/puppet_agent/manifests/params.pp, line: 69, column: 8) on node us03p01as01.prod.nextravel.com

Should I remove that class from PE master?

sigh, you have broken code

try that

you need to downgrade puppetlabs/stdlib later

See the

puppetlabs-stdlib

module at https://forge.puppet.com/puppetlabs/stdlib?src=slack&channel=puppet-enterprise

Same error

Can we downgrade after fixing this or would you recommend I do that right now

you need to downgrade to v8.6, because your code base is broken

since now you can't apply basic PE code

To downgrade, is the process 1) rm -rf modules/apt/ 2) puppet module install puppetlabs-apt --version 8.6.0 --modulepath=modules/

not apt, stdlib
