Hii there, I'm using Mendix 8 Studio Pro and when using the ‘Export to Excel button’ on my entity it DOES work in the local session but it doesn't in the ‘cloud’ version… I've used both an xPath dataview/dataview as from a microflow. Both work local, both don't work in the ‘cloud' version. My log gives the following error: Connector: An error has occurred while handling the request. [User 'Tom' with session id 'f55e032e-XXXX-XXXX-XXXX-XXXXXXXX9920' and roles 'Evelien, User, Administrator'] 15:22:56APPERRORConnector: com.mendix.systemwideinterfaces.MendixRuntimeException: Long

work. Anyone else has seen this behaviour? Thank you in advance!
