Prerequisites

Hi Team, I am getting the following issue as shown below for extend sample.

[
{
message: "Cannot read property 'existyStrict' of undefined",
validation: 'ENGINE_EXCEPTION',
field: 'start_time'
}
]
How can I fix. Please help. Thank you in advance for your support. Really very awesome and helpful validation library.

Package version

Node.js and npm version

Sample Code (to reproduce the issue)

const { validate, configure, validateAll, extend } = require('indicative/validator');
const { getValue, skippable } = require('indicative-utils');

const schema = {
username: 'required|alpha',
start_time: 'required|time',
//password: 'required|min:4|max:40',
}

const data = {
username: 'test',
start_time:'0er'
}

const timeRegex = /([01]?[0-9]|2[0-3]):[0-5][0-9](:[0-5][0-9])?/;

extend('time', {
async: false,

validate (data, field, args) {
    const fieldValue = getValue(data, field)
    if (skippable(fieldValue)) {
    return true
    }

    return timeRegex.test(fieldValue)
}
});

validate(data, schema, {'start_time.required':'start_time is required','start_time.time':'invalid start time format'}, {
    existyStrict: false,
    removeAdditional: false
  })
.then(console.log)
.catch(console.error)
