Puppet tasks fails because of missing gcompute_* functions

[khaefeli]

I've a puppetserver (6.1x) with a node connected, provisioning GCP. Which is working pretty well.

I tried now to orchestrate the instances with Puppet Tasks (based on Choria) for this node.

mco tasks run gcompute::instance --credential /root/credential.json --name testing --ensure present --project projectname --zone europe-west3-c -I infrastructurenode.internal

This runs the instance.sh script on the node (via Choria queue). But the Choria controller gets the following error:
choria.tasks/task-error: The task errored with a code 1 {"status":"failure"}

According to the /tmp/bolt-run log
Error: Evaluation Error: Unknown function: 'gcompute_task_load_params'. (line: 17, column: 11) on node infrastructure.internal

If I manually store the gauth and gcompute modules under /etc/puppetlabs/code/modules/ everything is working well. But I think this is not the target of a master/client setup. It probably should use the scripts from the master, which are stored under /opt/puppetlabs/puppet/cache/lib/
