MII Actions - XML to JSON Error

I get the following errors when I created MII Actions - XML to JSON:

XSLTransform error: Access to path /WEB://ProjectsStatus/WEB/XMLFiles/ProjectsStatus_Applications.xsl is not allowed.

Uncaught exception from XML_to_JSON_Application, Access to path /WEB://ProjectsStatus/WEB/XMLFiles/ProjectsStatus_Applications.xsl is not allowed.
