Spring Data Neo4j 5 and dynamic #Properties - InvalidDataAccessApiUsageException - neo4j

Question

This is my SDN 5 relationship entity:
#RelationshipEntity(type = "HAS_VALUE_ON")
public class RelationshipValue {
#Id
#GeneratedValue
private Long id;
#StartNode
private Decision decision;
#EndNode
private Valuable valuable;
#Index(unique = false)
private Object value;
public Object getValue() {
return value;
}
public void setValue(Object value) {
this.value = value;
}
}
Everything is working fine, but when I try to change the logic onto new dynamic #Properties :
#RelationshipEntity(type = "HAS_VALUE_ON")
public class RelationshipValue {
public static final String VALUE_PROPERTY_NAME = "value";
#Id
#GeneratedValue
private Long id;
#StartNode
private Decision decision;
#EndNode
private Valuable valuable;
#Properties(allowCast = true)
private Map<String, Object> valueProperties = new HashMap<>();
public Object getValue() {
return valueProperties.get(VALUE_PROPERTY_NAME);
}
public void setValue(Object value) {
valueProperties.put(VALUE_PROPERTY_NAME, value);
}
}
my tests fails with the following error:
org.springframework.dao.InvalidDataAccessApiUsageException: Could not map key=valueProperties.value, value=[Ljava.lang.Object;#52bef30b (type = class [Ljava.lang.Object;) because it is not a supported type.; nested exception is org.neo4j.ogm.exception.core.MappingException: Could not map key=valueProperties.value, value=[Ljava.lang.Object;#52bef30b (type = class [Ljava.lang.Object;) because it is not a supported type.

Is there any way to emulate the same correct behaviour(as in the first code snippet) with the dynamic #Properties ?

Answer 1

It is probably because arrays are not supported as Map values.
Switching from array to List as an argument to the setValue method should solve the problem.
