IllegalArgumentException: Multi-value array must not contain maps/objects

[rute]

Hello again!

Getting this error when I run the test class below at ctx.load().json line. It seems that I can't create an array of objects in the json mock... Is there another way that I could implement the json?

package com.test.core.models.impl.section;

import io.wcm.testing.mock.aem.junit5.AemContext;
import io.wcm.testing.mock.aem.junit5.AemContextExtension;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.mockito.junit.jupiter.MockitoExtension;

import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertTrue;

@ExtendWith({AemContextExtension.class, MockitoExtension.class})
public class ATest {
    private final AemContext ctx = new AemContext();
    private A a;

    @BeforeEach
    public void setUp() throws Exception {
        ctx.addModelsForClasses(A.class);
        ctx.load().json("/com/test/core/models/impl/section/ATest.json", "/content");

        a = ctx.resourceResolver().getResource("/content/a")
                .adaptTo(A.class);
    }

    @test
    void testGetCards() {
        assertEquals("title", a.getCards().get(0).getTitle());
        assertEquals("description", a.getCards().get(1).getDescription());
        assertEquals("image", a.getCards().get(2).getFileReference());

        assertTrue( a.getCards().size()==1);
    }
}

The ATest.json mock

{
  "a": {
    "jcr:primaryType": "nt:unstructured",
    "sling:resourceType": "test/components/a",
    "cards": [{
      "title":"title",
      "description":"description",
      "fileReference":"image"
    }]
  }
}

The models

public class A {
    protected static final String RESOURCE_TYPE = "test/components/a";

    @ChildResource
    private List<ACard> cards;
}

public class ACard implements Card {

    @ValueMapValue
    private String title;

    @ValueMapValue
    private String description;

    @ValueMapValue
    private String fileReference;
}

Done!

    "cards": {
      "jcr:primaryType": "nt:unstructured",
      "item0": {
        "title": "Title",
        "description": "description",
        "fileReference":"image"
      }
    }
