Workflow Version step issue/bug

I am in the process of a creating a couple workflows. My first step in the workflow is to create a version. Interestingly, It worked the first time I ran the workflow and it created the version correctly. Second time I ran the workflow, I started getting errors from the CreateVersionProcess class as below: it looks like the class unable to create a label for the version. I tried using both OOTB Version process and Process Step then on the Process dropdown chose Create Version. Has any one seeing or aware of this issue and what would be the solution for it.

JobHandler Process execution resulted in an error: java.lang.IllegalArgumentException: Unable to resolve label: org.apache.jackrabbit.spi.commons.conversion.IllegalNameException: empty name com.day.cq.workflow.WorkflowException: java.lang.IllegalArgumentException: Unable to resolve label: org.apache.jackrabbit.spi.commons.conversion.IllegalNameException: empty name at com.day.cq.wcm.workflow.process.CreateVersionProcess.execute(CreateVersionProcess.java:114) at com.day.cq.workflow.impl.job.HandlerBase.executeProcess(HandlerBase.java:184) at com.day.cq.workflow.impl.job.JobHandler.process(JobHandler.java:118) at org.apache.sling.event.jobs.JobUtil$1.run(JobUtil.java:272) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) Caused by: java.lang.IllegalArgumentException: Unable to resolve label: org.apache.jackrabbit.spi.commons.conversion.IllegalNameException: empty name at org.apache.jackrabbit.core.version.VersionHistoryImpl.hasVersionLabel(VersionHistoryImpl.java:235) at com.day.cq.wcm.workflow.process.CreateVersionProcess.createUniqueVersionLabel(CreateVersionProcess.java:145) at com.day.cq.wcm.workflow.process.CreateVersionProcess.execute(CreateVersionProcess.java:82) ... 6 more
