    (Tried to make chromedriver the component but it's not valid) The code in the chromedriver plugin is having trouble finding the os.name system property. Maybe it's not a bug but I can't figure out how to configure the node so that it gets picked up. Thank you. ERROR: Unexpected error in launching a slave. This is probably a bug in Jenkins. java.lang.NullPointerException at org.jenkinsci.plugins.chromedriver.DownloadableImpl.getType(DownloadableImpl.java:91) at org.jenkinsci.plugins.chromedriver.DownloadableImpl.select(DownloadableImpl.java:78) at org.jenkinsci.plugins.chromedriver.DownloadableImpl.resolve(DownloadableImpl.java:35) at org.jenkinsci.plugins.chromedriver.ComputerListenerImpl.process(ComputerListenerImpl.java:43) at org.jenkinsci.plugins.chromedriver.ComputerListenerImpl.preOnline(ComputerListenerImpl.java:34) at hudson.slaves.SlaveComputer.setChannel(SlaveComputer.java:367) at hudson.slaves.SlaveComputer.setChannel(SlaveComputer.java:314) at hudson.plugins.sshslaves.SSHLauncher.startSlave(SSHLauncher.java:454) at hudson.plugins.sshslaves.SSHLauncher.launch(SSHLauncher.java:293) at hudson.slaves.SlaveComputer$1.call(SlaveComputer.java:200) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:680)
