Hi @Purushotham,

the task queries from the REST API (Get Tasks | docs.camunda.org and Get Tasks (POST) | docs.camunda.org) contain a parameter assigneeExpression, but no taskAssigneeExpression.

Maybe just remove the task?

Hope this helps, Ingo

Hi @Ingo_Richtsmeier ,

If we use assigneeExpression , then the tasks are not loading in the tasklist. (not recommended)
if we use this “taskAssigneeExpression”:"${ currentUser() }" getting tasks in the tasklist properly,
but if i want to get those tasks from postman then getting below error.
URI : http://localhost:8080/engine-rest/filter/{filter Id}/list

"type": "ProcessEngineException",
    "message": "Unable to invoke method 'taskAssignee' on class 'org.camunda.bpm.engine.impl.TaskQueryImpl'"
