[JENKINS-56468] githubPRComment throws NPE

the following stage generates NPE, even when built against a PR:

stage ('mobileproduct - Prebuild') {

 githubPRComment comment: githubPRMessage('Build ${BUILD_NUMBER} ${BUILD_STATUS}')

}

 

the following NPE is generated:

java.lang.NullPointerException

Finished: FAILURE

the checkout phase checks out multiple projects, even though I am not sure it's supposed to matter.
