How to validate an enum value in a json schema validation?

Question

the main problem resides on validate a json against a schema that deals with arrays. So, if I put a different value seems to be still valid?

json schema:

{
  "transactions" : {
    "type" : "array",
    "items" : {
      "type" : "object",
      "properties" : {
        "type" : {
          "type" : "string",
          "enum" : ["BREAK"]
        },
        "required":["type"]
      },
      "required":["items"]
    }
  }
}

Input JSON:

{
  "transactions":[
    {
      "type":"BREAKDDDDDdddddddddddddddddddddddddddJDJDJDJDJDJDJDJ"
    }
  ]
}

result: No errors found. JSON validates against the schema.

This is wrong as we haven't defined an enum type like "BREAKDDDDD"

Any thoughts on this?

Solution

Your JSON Schema is missing certain attributes. Look at the example provided here on how to start the schema http://json-schema.org/example1.html.

Update your schema to the below and try

{
  "type": "object",
  "properties": {
    "transactions": {
      "type": "array",
      "items": {
        "type": "object",
        "properties": {
          "type": {
            "type": "string",
            "enum": ["BREAK"]
          }
        },
        "required": ["type"]
      }
    }
  }
}
