Artifacts Uploader fails with com.google.jenkins.plugins.credentials.oauth.GoogleRobotPrivateKeyCredentials$PrivateKeyNotSetException

I am using the plugin to upload the build logs as well as a folder container xml artifacts to the same GCS bucket using the same credentials within the same build. The build logs upload fine but the artifact uploads fail with the following error:
[Google Cloud Storage Uploader] Found 1 files to upload from pattern: artifacts/*.log ERROR: Build step failed with exception com.google.jenkins.plugins.credentials.oauth.GoogleRobotPrivateKeyCredentials$PrivateKeyNotSetException at com.google.jenkins.plugins.credentials.oauth.GoogleRobotPrivateKeyCredentials.getGoogleCredential(GoogleRobotPrivateKeyCredentials.java:184) at com.google.jenkins.plugins.credentials.oauth.GoogleRobotPrivateKeyCredentials.getGoogleCredential(GoogleRobotPrivateKeyCredentials.java:45) at com.google.jenkins.plugins.credentials.oauth.RemotableGoogleCredentials.<init>(RemotableGoogleCredentials.java:57) at com.google.jenkins.plugins.credentials.oauth.GoogleRobotCredentials.forRemote(GoogleRobotCredentials.java:204) at com.google.jenkins.plugins.storage.AbstractUpload.performUploads(AbstractUpload.java:413) at com.google.jenkins.plugins.storage.AbstractUpload.access$000(AbstractUpload.java:101) at com.google.jenkins.plugins.storage.AbstractUpload$1.call(AbstractUpload.java:367) at com.google.jenkins.plugins.storage.AbstractUpload$1.call(AbstractUpload.java:364) at hudson.remoting.UserRequest.perform(UserRequest.java:120) at hudson.remoting.UserRequest.perform(UserRequest.java:48) at hudson.remoting.Request$2.run(Request.java:332) at hudson.remoting.InterceptingExecutorService$1.call(InterceptingExecutorService.java:68) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at hudson.remoting.Engine$1$1.run(Engine.java:85) at java.lang.Thread.run(Thread.java:745) at ......remote call to mac-slave-01(Native Method) at hudson.remoting.Channel.attachCallSiteStackTrace(Channel.java:1416) at hudson.remoting.UserResponse.retrieve(UserRequest.java:220) at hudson.remoting.Channel.call(Channel.java:781) at hudson.FilePath.act(FilePath.java:1074) at com.google.jenkins.plugins.storage.AbstractUpload.initiateUploadsAtWorkspace(AbstractUpload.java:363) at com.google.jenkins.plugins.storage.AbstractUpload.perform(AbstractUpload.java:182) at com.google.jenkins.plugins.storage.GoogleCloudStorageUploader.perform(GoogleCloudStorageUploader.java:109) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:20) at hudson.model.AbstractBuild$AbstractBuildExecution.perform(AbstractBuild.java:782) at hudson.model.AbstractBuild$AbstractBuildExecution.performAllBuildSteps(AbstractBuild.java:723) at hudson.model.Build$BuildExecution.post2(Build.java:185) at hudson.model.AbstractBuild$AbstractBuildExecution.post(AbstractBuild.java:668) at hudson.model.Run.execute(Run.java:1763) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:43) at hudson.model.ResourceController.execute(ResourceController.java:98) at hudson.model.Executor.run(Executor.java:410) Build step 'Google Cloud Storage Uploader' marked build as failure

This seems to happen after moving to Jenkins v2.0+ - not sure if that is related though
