Hey @MichelDiz, I see that you are using Projeto_Owner predicate for traversing the relationship in both directions which is not how it works. You should use ~Projeto_Owner to traverse in reverse direction. I will illustrate with an example.
child: uid @reverse .
set {
_:f <name> "Father" .
_:f <child> _:c .
_:c <name> "Child" .
Then if I started with the father, the query would be
{
me(func: uid(father_id)) {
name
child {
name
}
}
If I started with child, the query would be
{
me(func: uid(child_id)) {
name
~child {
name
}
}
