I want to create a simple web app using the quasar framework. to validate form inputs, I'm planning to use vuelidate and vuelidate-Error-Extractor. so I have installed these packages and created a boot file using quasar CLI "vuelidate-error-extractor". and also and add that filename into the plugin in quasar config

but there is a problem when initializing vuelidate-Error-Extractor. can someone help me to fix this

this is the error which i got when try to config this

console errros

this is the boot file

import { boot } from 'quasar/wrappers'
import Vuelidate from 'vuelidate'
import VuelidateErrorExtractor, { templates } from "vuelidate-error-extractor";

const messages = {
  required: '{attribute} is required.',
  requiredCustom: '{attribute} is required.',
  min: "Field {attribute} should be exceeded 5 characters",
  onlynumbers: '{attribute} should be numbers.',
  maxLength: '{attribute} should be less than {max} characters.',
};





// "async" is optional;
// more info on params: https://v2.quasar.dev/quasar-cli/boot-files
export default boot( ({app,Vue}/* { app, router, ... } */) => {
  // something to do
  app.use(Vuelidate)
  app.use(VuelidateErrorExtractor, {
    messages,
    attributes: {
      name: "Name",
      email: "Email",
      text: "Text"
    }
  });

  app.component("formWrapper", templates.FormWrapper);
})

I was just getting this same error while trying to get Hello.js working with Quasar. In my case it was happening because I had code that was trying to set a property on app.prototype, but with Quasar boot code you need to set the property on app.config.globalProperties instead. (Here's an example in Quasar's documentation section on Boot files)

So I had to change:

app.prototype.$hello = hello

to:

app.config.globalProperties.$hello = hello

So my guess is that in your case there's some similar line in the Vuelidate code that needs to be changed.
