Format for validation results

What version of Ajv you are you using? 8.17.1

What problem do you want to solve? The current validate result is an array, but I expect the error result to correspond to the input field. Is that feature already provided?

What do you think is the correct solution to problem? example validation code

import Ajv from 'ajv'
const ajv = new Ajv({ allErrors: true })

const schema = {
  type: 'object',
  properties: {
    foo: { type: 'integer', minLength: 5 },
    bar: { type: 'integer' },
  },
  required: ['foo'],
  additionalProperties: false,
}

const data = {
  foo: 'a',
  bar: 'b',
}

const validate = ajv.compile(schema)
const valid = validate(data)
if (!valid) console.log(validate.errors)

current validation result

[
  {
    instancePath: '/foo',
    schemaPath: '#/properties/foo/type',
    keyword: 'type',
    params: { type: 'integer' },
    message: 'must be integer'
  },
  {
    instancePath: '/foo',
    schemaPath: '#/properties/foo/minLength',
    keyword: 'minLength',
    params: { limit: 5 },
    message: 'must NOT have fewer than 5 characters'
  },
  {
    instancePath: '/bar',
    schemaPath: '#/properties/bar/type',
    keyword: 'type',
    params: { type: 'integer' },
    message: 'must be integer'
  }
]

ideal result

{
  foo: [
    {
      instancePath: '/foo',
      schemaPath: '#/properties/foo/type',
      keyword: 'type',
      params: { type: 'integer' },
      message: 'must be integer',
    },
    {
      instancePath: '/foo',
      schemaPath: '#/properties/foo/minLength',
      keyword: 'minLength',
      params: { limit: 5 },
      message: 'must NOT have fewer than 5 characters',
    },
  ],
  bar: [
    {
      instancePath: '/bar',
      schemaPath: '#/properties/bar/type',
      keyword: 'type',
      params: { type: 'integer' },
      message: 'must be integer',
    },
  ],
}

Will you be able to implement it? It is possible to add the optional setting to change the format of the validation results as part of the Validation and reporting options.
