Let’s say we have the following JSON Schema:

{
    "type": "array",
    "items": {
      "type": "object",
      "properties": {
        "name": { "enum": ["Adam", "Daniel", "Mike"] },
        "desc": { "type": ["string", "null"] }
      },
      "required": [
        "name"
      ]
    }
}

Is it possible to validate that the field “name” has the same value for all objects in the array?

Examples:

1. Valid

[
  {"name": "Adam"},
  {"name": "Adam", "desc": "good"},
]

2. Valid

[
  {"name": "Mike"},
  {"name": "Mike", "desc": "good"},
]

3. Invalid

[
  {"name": "Adam"},
  {"name": "Adam", "desc": "good"},
  {"name": "Mike", "desc": "bad"},
]
