"produces" statements seem not to work from a puppet agent run

Trying to export a capability when running puppet agent results in the following error:

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Resource type Site::Pql does not produce Sql on node centos7-1.vm

There is a Site::Pql produces Sql statement in the correct spot (next to the definition), but it seems not to have actually been evaluated.

If environment_timeout = unlimited is enabled and an environment catalog is retrieved first, subsequent agent runs succeed. This seems to indicate that the produces statements are evaluated when compiling the environment catalog and then cached for the agent run.
