Hi Kai,
The component information looks fine.
You could try the below URL to get the query data for your QueryTemplate (Default/ODa)
http://<host>:<port>/XMII/IlluminatorOData/Rowsets('Default/ODa')/Rowset or
http://<host>: <port>/XMII/IlluminatorOData/Rowset(QueryTemplate='Default/ODa',RowsetId=1)/Row
Hope this helps!
Thanks and Best Regards,
Ria
