Are you overridding "supported_checksum_types" on either the server or agent? Probably best to see the complete `puppet.conf` for server and agent when the error occurs. What puppet-agent and puppetserver versions do you have installed? Are static catalogs enabled either globally (puppet config get static_catalogs --section master|agent) on either the server or agent, or per-environment in "$codedir/environments/test/environment.conf" ? Did you happen to install the JrJackson gem on the server?
