Priority with Name Null is not Available for Scheme
Problem: If, when running an import, you receive an error similar to the one below, this indicates the default priority for one of the projects being exported has not been configured.
com.awnaba.projectconfigurator.utils.errorhandling.XMLInputDataException: Priority with name null is not available for scheme Default priority scheme. Maybe it does not exist
Solution: To work around this error, you should review the projects being exported inside the source instance to identify any projects which do not have a default priority configured.
For each project identified, you must add a default priority to the priority scheme each project uses before generating a new export file to import from.
