Bug: Schema export does not include nested properties for array-object items

[Jakob-42]

Description:

When exporting a schema that contains an array of objects with nested properties, only items: { bsonType: "object" } is exported. All nested property definitions inside the array items are missing from the export.

Steps to Reproduce:

1. Load the "theaters" example schema (or any schema with arrays containing objects with nested properties)
2. Verify the schema includes an array field with object items that have defined nested properties
3. Export the schema
4. Compare the exported code to the expected output

Current Output:

"location": { bsonType: "array", items: { bsonType: "object" } }

Expected Output:

"location": { 
  bsonType: "array", 
  items: { 
    bsonType: "object",
    properties: {
      "address": { 
        bsonType: "object",
        properties: {
          "street1": { bsonType: "string" },
          "city": { bsonType: "string" }
        }
      }
    }
  }
}

Note:

Export works correctly for non-array objects. Nested properties are included when the field is a direct object type.

I manage to reproduce it using the default mongo modeler example (movies), exactly just updating in the theather collection, the file location to an array, then I got this:

db.createCollection("theaters", {
  validator: {
    $jsonSchema: {
      bsonType: "object",
      title: "theaters",
      required: ["_id"],
      properties: {
        "_id": { bsonType: "objectId" },
        "teatherId": { bsonType: "int" },
        "location": { bsonType: "array", items: { bsonType: "object" } },
      },
    },
  },
});

Could you confirm that the expected response should be something like?

db.createCollection("theaters", {
  validator: {
    $jsonSchema: {
      bsonType: "object",
      title: "theaters",
      required: ["_id"],
      properties: {
        "_id": { bsonType: "objectId" },
        "teatherId": { bsonType: "int" },
        "location": { 
          bsonType: "array",
          items: { 
            bsonType: "object",
            required: ["address"],
            properties: {
              address: {
                bsonType: "object",
                required: ["street1", "city"],
                properties: {
                  street1: { bsonType: "string" },
                  city: { bsonType: "string" }
                }
              }
            }
          }
        }
      }
    }
  }
})

Thanks

Yes, exactly like that.

Appreciate you looking into this!
