Note that no output is seen directly in the script and no output recorded to a logfile. Instead the output is stored as a job by the web service. For example the following script would retrieve the output for the run job.

set UserDefaultDir [ file dirname [ info script ] ]
::tcl::tm::path add "$UserDefaultDir/modules"
package require rest
package require huddle
    set res [rest::get http://localhost:8080/jobs?jobid=5D1F4FF558CE03E223730313 "" ]
puts "JSON format"
puts $res

With the output as follows.
