Object with required fields passes validation and is missing default empty object

[kylie-marshall]

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• I have read the documentation
• Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

What theme are you using?

core

Version

5.13.2 (latest on playground)

Current Behavior

Validation passes and no default object is created

Expected Behavior

Validation should error
In version 4, the object added a default {} to the form data which allowed ajv to trigger the validation. Now, the empty object is not being added by default.

Steps To Reproduce

1. Have a schema with an object and a property inside that object is required but the object itself is not required
2. Disable HTML 5 validation
3. Form data is empty {} or undefined
4. Save the form without adding any data
5. Observe form passed validation and no errors were displayed

Environment

Playground environment

Anything else?

Playground link with example

Example schema

{
  "title": "A registration form",
  "description": "A simple form example.",
  "type": "object",
  "properties": {
    "testobject": {
      "type": "object",
      "required": [
        "firstName",
        "lastName"
      ],
      "properties": {
        "firstName": {
          "type": "string",
          "title": "First name"
        },
        "lastName": {
          "type": "string",
          "title": "Last name"
        }
      }
    }
  }
}

I've tested with both ajv6 and ajv8 with the same result

Tried to update the emptyobjectfields property but this didnt fix it. This setting says that it should populate defaults for non-empty objects (which worked in v4 as the legacy behavior) but it doesnt anymore

@kyliem29 Hi, the behavior you were expecting that was present in v4 was actually a bug that many others had reported. To get your schema to work, you will need to require the testobject property.

See this playground example
