Issue
I'm new working with Spring boot, I'm having trouble in getting a list of objects which this objects is related to another object. To make a better explanion I'll show the adding request, which is working fine:
Sorry for the language my college teacher suggested to use portuguese language, the main thing is a software where there are customers and inside of this object there is an address. OneToOne related
{
"nome":"Adriano",
"complemento":"DevOps",
"numero": 123,
"endereco": {
"cep":88787123,
"logradouro": "Rua petuinha",
"uf": "SC",
"bairro": "Dourado",
"cidade": "PH"
}
Fortunately, both records for customer and address were inserted into database with the correct relationship between them.
The main problem is in the getAll customer Endpoint, which only occurs error when there is at least one Customer with not null address inside it, this the customer has a null address the problem do not happen:
Check add and getAll customer Endpoints
Probably the error occurs in the getAll endopoint, I'm returning a list of objects, and when I do the request for this endpoint this message happen:

To this post not be so big, I'm sharing my repository with all files:
https://github.com/adrielkirch/crud-springboot-clientes
Graciously from Brazil
Solution
I Solved this issue adding this to de model class:
@Entity
@Table (name = "cliente")
@JsonInclude(JsonInclude.Include.ALWAYS)
public class Cliente implements Serializable{...
And adding this to the application.properties
*spring.jackson.serialization.fail-on-empty-beans=false*
