Array of oneOfs with required fields fails validation about jsonschema HOT 4 CLOSED

{
    "foobar": [
        {
            "first": "A",
            "second": true
        },
        {
            "first": "X"
        }
    ]
}

the complete error I get when %#v is used:

[I#] [S#] doesn't validate with https://foo.com/test/definitions.json#
  [I#/foobar/1] [S#/properties/foobar/items/oneOf] oneOf failed
    [I#/foobar/1] [S#/properties/foobar/items/oneOf/0]
      [I#/foobar/1] [S#/properties/foobar/items/oneOf/0/required] missing properties: 'second'
      [I#/foobar/1/first] [S#/properties/foobar/items/oneOf/0/properties/first/const] value must be "A"
    [I#/foobar/1/first] [S#/properties/foobar/items/oneOf/1/properties/first/const] value must be "B"
    [I#/foobar/1/first] [S#/properties/foobar/items/oneOf/2/properties/first/const] value must be "C"```

this is the expected result. the instance json you passed does not validate with the provided schema:

let me clarify why it is invalid:

second item {"first": "X" } does not satisfy:

• first schema of oneOf because: "second" property is missing && value of first must be A But it is X
• second schema of oneOf because: value of first must be B but it is X
• third schema of oneOf because: value of first must be C but it is X
  i.e none of oneOf schemas satisfied. so validation fails.

just to clarify: both const and required are independent validations and both must be satisfied.

Ah I'm sorry @santhosh-tekuri , that was an incorrect reproduction I gave you to begin with. Should have checked that twice.
I'll open a new ticket with a correct reproduction. Thanks for the quick and thorough reply.

if you are ok in sharing your schema and instance, then you can raise issue. no need to struggle for minimal reproduction

After actually looking through this the problem is on our side. 🤦
It was the same scenario but on of the oneOf had an extra field that could be type [ "string", "null"] and which was also required, and that was not being sent in the payload, so of course that won't pass validation.
