No http lib found to perform ajax request in VJSF

Solution for No http lib found to perform ajax request in VJSF
is Given Below:

I use VJSF to fill selects using the results from HTTP requests.
Then I faced a bug that is stressful.
enter image description here
Following is my code.

  <v-app id="app">
      <v-form ref="form" v-model="valid">
        <v-jsf v-model="model" :schema="schema" :options="options" @input="logEvent('input', $event)" @change="logEvent('change', $event)" />
      <v-layout row class="mt-2">
        <v-btn color="primary" @click="$refs.form.validate()">Validate</v-btn>


import VJsf from '@koumoul/vjsf/lib/VJsf.js'
import '@koumoul/vjsf/lib/VJsf.css'
import '@koumoul/vjsf/lib/deps/third-party.js'

const model = {
    selectAjaxString: ''

const options =  {
    context: {
        owner: {
            type: 'organization',
            id: '5a5dc47163ebd4a6f438589b'
    idPrefix: 'example-select-http-'

const schema = {
    type: 'object',
    properties: {
        selectAjaxString: {
            type: 'string',
            title: 'I'm a string selected from results of an HTTP request',
            'x-fromUrl': '{context.owner.type}:{}',
            'x-itemsProp': 'results',
            'x-itemTitle': 'title',
            'x-itemKey': 'href'

export default {
  name: 'App',
  components: { VJsf },
  data: () => ({
    valid: false
  methods: {
    logEvent(key, $event) {
      console.log("vjsf event", key, $event);

What is the reason?
Why I can not perform ajax request?
I followed sample in

It looks like VSJF requires users to specify an HTTP request library via the httpLib configuration option:

  1. Install axios:

    npm i -S axios
  2. Update your VSJF configuration options to set axios as the httpLib:

    import axios from 'axios'
    const options = {
        httpLib: axios
