push job output not captured on postgres

[railsmith]

Despite passing the --capture flag while triggering a push job the stdout and the stderr are not at all stored in the postgres. Do I need to configure or enable something on the push-jobs-server to start capturing the job output?

chef-server 12.8.0 opscode-push-jobs-server 2.1.0 push-jobs-client 2.1.1

select * from job_output;

          job_id                                         |            node_name             | stdout     | stderr
