L3 - Default Description
As also described in this forum post: https://groups.google.com/forum/#!topic/camunda-bpm-users/xk3utUlZvew
A ProcessEngineException occurs when I try to get all tasks assigned by candidateGroups to the current authenticated user.
Please note: The current authenticated user has no (zero) groups.
Expected behavior is a normal (http 200) response with an empty result list.
Here is the rest-call: /engine-rest/task?candidateGroupsExpression=%24
{currentUserGroups()}
The JSON error response:
{"type":"ProcessEngineException","message":"Unable to invoke method 'taskCandidateGroupIn' on class 'org.camunda.bpm.engine.impl.TaskQueryImpl'"}This is the stack trace from the engine:
Caused by: org.camunda.bpm.engine.ProcessEngineException: Candidate group list is empty
