Try running as sudo. I faced this error when trying to apply settings using --environment. Using sudo resolved the error. I know that's weird. — Vikas, Aug 08 '17 at 17:47
I'll second the comment about sudo. I ran the agent as non-root and got the same error. — GargantuChet, Jun 15 '18 at 21:04

The root cause is that the puppet version on puppet master server is 3.8.1 However i install puppet 4.1.0 on puppet agent.

Puppet master version must be greater than or equal puppet agent version. The solution is that i uninstall puppet on puppet agent and reinstall puppet version 3.8.1 instead.

In my case this problem was caused by missing environment variable in puppet.conf. After running with --environment production all works as expected.
