D4Science Infrastructure

There are issues with the Workspace interaction, perhaps due to the release of December.
When I execute a computation from a VRE through the portal, the HL returns this error:

org.gcube.common.homelibrary.home.workspace.exceptions.ItemNotFoundException: java.lang.String cannot be cast to org.gcube.common.homelibary.model.items.ItemDelegate
org.gcube.common.homelibrary.home.exceptions.InternalErrorException: org.gcube.common.homelibrary.home.workspace.exceptions.ItemNotFoundException: java.lang.String cannot be cast to org.gcube.common.homelibary.model.items.ItemDelegate

Nevertheless, the issue does not appear by calling the DataMiner directly via http, e.g.:

http://dataminer1-p-d4s.d4science.org/wps/WebProcessingService?request=Execute&service=WPS&Version=1.0.0&gcube-token=26209520-6e2d-4850-9716-0b2bd37fd017-843339462&lang=en-US&Identifier=org.gcube.dataanalysis.wps.statisticalmanager.synchserver.mappedclasses.clusterers.DBSCAN&DataInputs=OccurrencePointsTable=http://data.d4science.org/a0pFQ0RuUXhpOEpmcElhcUlmQUpWc3VLd0FWM04xMnlHbWJQNStIS0N6Yz0;FeaturesColumnNames=a|b|t;OccurrencePointsClusterLabel=OccCluster_;epsilon=10;min_points=1;

The issue is not there neither when using the proxy instead of the direct service address.

The complete stack trace of the Exception is:

I guess the HL is not updated on DataMiner, which once gave the same issue and this issue is somehow related to the VRE and authentication indicated by the portal. @roberto.cirillo@isti.cnr.it and @valentina.marioli@isti.cnr.it could you help us please?

I've done some tests.

When an execution is performed by portal I see an exception on HomeLibrary webapp:

when the same execution is perfomed by url I don't see this exception:

@valentina.marioli@isti.cnr.it do you think this exception could be the problem?
