Incorrect validation multi array of objects

[PetrChalov]

Hi! I encountered incorrect validation of an array of objects.

Code:

const Validator = require('fastest-validator');
const v = new Validator();

const schema = {
  $$root: true,
  type: 'array',
  items: {
    type: 'multi',
    rules: [
      {
        type: 'object',
        props: {
          data: {
            type: 'object',
            props: { position: { type: 'number' } },
          },
          meta: {
            type: 'object',
            props: { op: { type: 'equal', value: 'up' } },
          },
        },
      },
      {
        type: 'object',
        props: {
          data: {
            type: 'object',
            props: { value: { type: 'string' } },
          },
          meta: {
            type: 'object',
            props: { op: { type: 'equal', value: 'down' } },
          },
        },
      },
    ],
  },
};

const check = v.compile(schema);

const data = [
  {
    data: { position: 1 },
    meta: { op: 'down' },
  },
  {
    data: { value: 'val' },
    meta: { op: 'down' },
  },
];

console.log(check(data));
// Print
// [
//   {
//     type: 'equalValue',
//     message: "The '[0].meta.op' field value must be equal to 'up'.",
//     field: '[0].meta.op',
//     expected: 'up',
//     actual: 'down'
//   },
//   {
//     type: 'required',
//     message: "The '[0].data.value' field is required.",
//     field: '[0].data.value',
//     actual: undefined
//   }
// ]

Is there any way to make this work?

In your case the checked data is really wrong because the first object meta.op should be "up", but in your case is "down". When FV checks the multi rules, it can't detect which is wrong of both. Because the sight of the first rule, the meta.op value is wrong, but the sight of the second rule, the data.value is wrong. So the result is fine.
