Setup: Jenkins DSL Job using sauceOnDemand {credentials(Credentials ID associated with the sauclabs credentials stored in Jenkins)}

I have written a DSL job to run Automated Tests via Jenkins on SauceLabs. I am using suaceOndemand and trying to pass sauceLabsCredentials with each Job that I execute but the build fails with the following error:
No signature of method: javaposse.jobdsl.dsl.helpers.wrapper.SauceOnDemandContext.credentials() is applicable for argument types: (java.lang.String) values: [My crdentials ID]
I restarted Jenkins after installing the plugin. Not sure if I am missing something here.

I came across a similar issue JENKINS-36370 but not sure if that's related.
