Anylogic Empty collection error (java.util.NoSuchElementException)

To start on i will discribe my model. I'm working on a simulation based on a last mile fleet delivery and I am using collections inside a population (vans) of agents called Van. In this collections (route) I am storing agents called orders that they have the parameters latitude and longitude of the final destination. I'm taking all the data from a DB and introducig it on a source block. On the exit of the source block the following code is implemented for adding the agents to the collection by an unique ID:

findFirst(vans, v -> v.Key == agent.VanKey).route.addLast(agent);

Before the last mile delivery the orders are processed by a crossdock.

For the pickup i am using a pickup block as i have a specific timestamp for the vans. When I want to assing the first delivert taking the first agent from the collection i have the following error:

java.util.NoSuchElementException

I notice that anylogic dont found any element in the collection but when I look inside the population of all the vans I see that the elements are in the collection.

How can i access to this elements? How can i fix this error?

I'm leaving some prints for better understanding of the problem.

Solved, the agents from the source of the last mile delivery where not the same agents as the population which have the collections fullfield inside.
