Grouper : Error : Generation of source-path failed

Grouper - Documentation

When Grouper was attempting to calculate the path portion of the URL from which to retrieve data, no path was generated.

There is an error in the "build query function" for the data source you are using (as determined by the "source" configuration setting or, more likely, a plugin loaded using GrouperLoadPlugin): Contact the creator of the plugin and resolve the issue with them.
