Symfony 5.4 - How to fix Neither the property nor one of the methods exist and have public access in class "Symfony\Component\Form\FormView"?

Question

I'm having trouble understanding what I'm doing wrong here. I have a "Project" entity that has a relation (ManyToMany) with another entity, "Service". In turn, Service is related to a "Task" entity, which is itself related to a "Section" entity. In the ProjectType I create a form field using FormBuilder for the property that identifies the Project - Service relation. In the twig template I'm trying to access Service's properties. I can't seem to access the property "section" of the task property in Service.

                            </div>

but this is the error I'm getting:

Neither the property "section" nor one of the methods "section()", "getsection()"/"issection()"/"hassection()" or "__call()" exist and have public access in class "Symfony\Component\Form\FormView".

Am I completely stupid and I'm missing something obvious or did I do everything wrong?
