`If` `then` `else` not working in case of list in json schema

Question

Json Schema and Json
I am trying to put a required check on certain variables based on what value is present in another attribute.
If paymentType= Shopping_cards then mandate paymentRef1 and
if it is not then mandate other attributes. But when paymentType != Shopping_cards then also I am getting error for paymentRef1.
Not sure what I am doing wrong here.
Can somebody please help me out? Both JSON schema and the request are present in the above link.

Answer 1

The if is inside properties > payment > properties > paymentMethods > items, so why not specify the condition relative to items. Change:

"if": {
  "properties": {
    "paymentMethods": {
      "items": {
        "properties": {
          "paymentType": {
            "const": "SHOPPING_CARDS"
          }
        }
      }
    }
  }
},

to:

"if": {
  "properties": {
    "paymentType": {
      "const": "SHOPPING_CARDS"
    }
  }
},

It works. I have no idea why the condition is true in the original version though.
