Hi @kotireddy4b1,

ProjectTaskWorkflowProcess logic adapts the project path resource to Project type (com.adobe.cq.projects.api.Project). 

Given that it is executed outside the project console independently, we have an Exception. (In particular, NPE)

You can try creating a custom project as illustrated in the below doc (have the Task creation as part of Workflow within the created custom Project)

@kotireddy4b1 the first error indicates you have selected too many assets in your collection. Can you please try selecting 10 assets, create a test collection and then initiate the workflow again?

AEM OOTB allows to run a workflow on max 15 assets. Please share your findings afterwards.
