Redis – Need to configure regular expression that can be applied to each line in the build log to set build description as jenkins pipeline script

Could use Jenkins description setter plugin in Jenkins UI to set the build description to the matched regex from build logs, but I failed to replicate the same functionality as Jenkins script, used the below lines but ended up with errors.

publishers {
                buildDescription(/^build-descrip: (.*)/)
            } 


O/p

[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
