Spring boot: 3.2.0, Spring data Couchbase: 5.2.0: java.lang.IllegalArgumentException: Attribute of type java.util.Collections.SingletonList cannot be stored and must be converted.

Hi,

I am using Spring boot: 3.2.0 with Spring data Couchbase: 5.2.0

I have an entity defined with a field of type Object (this field can be everything (String or List...)):

public class Person {
    @NotNull
    @Id
    private String id;

    @NotNull
    @Field
    private String name;

    @Field
    private int age;

    @Field
    private Object myObject;
}

while trying to save it using this:
personRepository.save(new Person("1", "Alice", 25, Collections.singletonList("my issue")));

It failed on java.lang.IllegalArgumentException: Attribute of type java.util.Collections.SingletonList cannot be stored and must be converted.

it was working with previous version: Spring boot: 2.7.13, Spring data Couchbase: 4.4.13.
demo.zip

Find attached the project where it failed: to reproduce, run PersonRepositoryTest

Any suggestion?

Thank you
