The pipeline plugin allows me to see the console output for individual steps, e.g:

http://myjenkins/jenkins/job/myjob/505/execution/node/161/log/?consoleFull

This page shows a link "View as plain text", which works on the global per-job console log, but in the per-step log viewer I get this 404 error message if I follow that link:

http://myjenkins/jenkins/job/myjob/505/execution/node/161/log/consoleText

404 The requested resource is not available.
