Hello Azeem, If you want to get familiar with task queues, you are encouraged to follow a complete example. The one provided in documentation is: "Enqueue.java" on github <https://github.com/GoogleCloudPlatform/java-docs-samples/blob/master/appengine-java8/taskqueues-push/src/main/java/com/example/appengine/taskqueue/push/Enqueue.java>. Related clarification is provided in the "Creating Tasks" on-line document <https://cloud.google.com/appengine/docs/standard/java/taskqueue/push/creating-tasks> .
In particular, the code portion dealing with task creation is a little more complex: import com.google.appengine.api.taskqueue.Queue; import com.google.appengine.api.taskqueue.QueueFactory; import com.google.appengine.api.taskqueue.TaskOptions; Queue queue = QueueFactory.getDefaultQueue(); queue.add(TaskOptions.Builder.withUrl("/worker").param("key", key)); It seems that writing to the datastore fails. It might be advisable to modify the line: ofy().save().entity(post).now(); and modify it in similar to: @Entity class Car { @Id String vin; // Can be Long, long, or String String color; } that is by creating a class for the entity and instantiating it with a "new" statement: ofy().save().entity(new Car("123123", "red")).now(); More information is to be found in the github page <https://github.com/objectify/objectify> for Objectify, under "Features".
