Json Schema Validation Invalid type. Expected Array but got Object

Question

I've got some Json

{
"store_purchase_control": {
    "pass_except_these": [
        [
            {
                "vendor_name_list": {
                    "value_contains": [
                        "Amazon",
                        "Amazon Toys"
                    ]
                }
            }
        ]
    ]
}

}

I'm trying to validate against json schema..

}

Parsing this using ..

https://www.jsonschemavalidator.net/

JSON does not match any schemas from 'anyOf'.

Schema path: #/definitions/pass_except_these/items/items/anyOf

Message: Invalid type. Expected Array but got Object. Schema path: #/definitions/store_id_list/type

Message: Invalid type. Expected Array but got Object. Schema path: #/definitions/store_list/type

Message: Invalid type. Expected Array but got Object. Schema path: #/definitions/vendor_name_list/type

It seems to be unable to resolve the anyOf keyword

It's not clear what you're trying to do with this, but it appears that you're trying to add some of the schema constraints to the data.

This is the corrected data that matches the schema:

{
  "store_purchase_control": {
    "pass_except_these": [
      [
        [
          "Amazon",
          "Amazon Toys"
        ]
      ]
    ]
  }
}

The pass_except_these property expects an array of arrays, where each item in the secondary array is one of:

• vendor_name_list which is an array of strings
• store_list which is an array of range values
• store_id_list which is an array of strings

So you have an array of arrays, where each item is also an array. You have three levels of arrays.

From the naming of things inside the schema, I expect that this might not be what you're trying to do, but that's the data that satisfies the schema. If you suspect the schema might be wrong, the question is not clear about that.
