Could you try with the recently released Liferay 7.2 GA 2 (or in case of DXP, upgrade to the most recent patch?).
A Nullpointer Exception in KaleoInstanceTokenModelDocumentContributor was fixed after the release of GA1.

Hi Ali,
The upgrade planner will help you to migrate your old Liferay workspace and custom code in 7.1 to 7.2, if you need help on that, use it.
Cheers.

Hi
I had a workflow module that was working properly on liferay 7.1
But now I created Workspace and Module in accordance with liferay 7.2
When I start workflow according to the code below

WorkflowHandlerRegistryUtil
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .startWorkflowInstance( importation.getCompanyId(), importation.getGroupId(), importation.getUserId(), Importation.class.getName(),
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; importation.getPrimaryKey(), importation, serviceContext );

I have encountered the following exception!!!!!
