Workflow Authorization error

Workflow Authorization error

While working with Workflow in AEM 6 and above or CQ5.6, it is important to ensure all the user access is provided correctly in either case following error can be encountered. In my case, the user group itself was not present. Again, this was because I had copied workflow from other location and not created it on my instance from the scratch.
