I have below code in my spring-boot application . We are not getting any exception at startup but while creating attribute I am getting below exception like  
Caused by: org.hibernate.search.util.common.SearchException: HSEARCH400609: Unknown field ‘attributes.archetype.archetypeId’.

I am not sure if I miss anything else…

**Resource.java(Entity class)**

```auto
    @MapKeyColumn(name = "attribute_name")
    @Column(name = "attribute_value", nullable = false, length = 5000)
    @PropertyBinding(binder = @PropertyBinderRef(type = ResourceAttributesBinder.class))
    @Convert(attributeName = "value", converter = JSONObjectConverter.class)
    @EqualsAndHashCode.Exclude
    @ToString.Exclude
    @OptimisticLock(excluded = true)
    private Map<String, JSONObject> attributes;

```

```auto

```

**ResourceAttributesBinder.java**

```auto
public class ResourceAttributesBinder implements PropertyBinder {
    @Override
    public void bind(PropertyBindingContext context) {
        context.dependencies().useRootOnly();
        PojoModelProperty bridgedElement = context.bridgedElement();
        IndexSchemaObjectField attributeField = context.indexSchemaElement()
                .objectField( bridgedElement.name() );
        context.bridge(Map.class,new ResourceAttributesPropertyBridge(attributeField.toReference()));
    }
}

```

**ResourceAttributesPropertyBridge.java**

```auto
@Override
    public void write(DocumentElement target, Map bridgedElement, PropertyBridgeWriteContext context) {
        final Map<String, Object> indexMap = (Map<String, Object>) bridgedElement;
        DocumentElement indexedAttributeMetadata = target.addObject( fieldReference );
        ....        
        ....
        
        indexedAttributeMetadata.addValue(fieldName,attributeValue.toString());    
}
```
