Sorry I've answered on the wrong issue

This issue has been fixed and released as part of v5.12.0 release.

Please note that passing oneOf at the root level with mixed type (array or object) is not supported, so use one of the following syntax:

1. Solution 1

{
  type: 'object',
  properties: {
    foo: {
      oneOf: [
        { type: 'object' },
        { type: 'array' }
      ],      
    }
  }
}

2. Solution 2

{
  type: 'object',
  oneOf: [
    { properties: { foo: { type: 'object' } } },
    { properties: { foo: { type: 'array' } } },
  ],
}

Thank you!
