Validator.register: TypeError: Cannot set properties of undefined

[vedmant]

What version of this package are you using?

"validatorjs": "^3.22.1",

What operating system, Node.js, and npm version?

MacOs 12.4
Node v18.13.0
Yarn 1.22.19

I'm using Vite for the build.

What happened?

I have following code:

import * as Validator from 'validatorjs'

Validator.register('amount', value => value.match(/^-?[0-9.,]*$/), 'The :attribute must be a number.');

This gives me error on the Validator.register line above:

Uncaught (in promise) TypeError: Cannot set properties of undefined (setting 'amount')
    at Object._setRuleMessage (lang.js:36:34)
    at Validator.register (validator.js:604:8)
    at policy-validation.js:40:11
_

In the source code it errors on line:

this.messages[lang][attribute] = message;

So probably means this.messages[lang] was never set.

What did you expect to happen?

No errors.

Are you willing to submit a pull request to fix this bug?

Maybe if it's simple.

This edit fixes my issue:

// lang.js

...
  _setRuleMessage: function(lang, attribute, message) {
    this._load(lang);
    if (message === undefined) {
      message = this.messages[lang].def;
    }
    // Added this line
    if (typeof this.messages[lang] === 'undefined') {
      this.messages[lang] = {}
    }
    this.messages[lang][attribute] = message;
  },
....

I'm facing the same issue, this workaround works fine for me:

import { defineConfig } from 'vite';

export default defineConfig({
  resolve: {
    alias: {
      validatorjs: 'validatorjs/dist/validator.js',
    },
  },
});

Same issue here,

undefined ERROR Uncaught Exception {"errorType":"TypeError","errorMessage":"Cannot set properties of undefined (setting 'notEmptyString')","stack":["TypeError: Cannot set properties of undefined (setting 'notEmptyString')"," at Object._setRuleMessage (file:REDACTED**)"," at Validator.registerImplicit (file:REDACTED**)"," at file:REDACTED**" at ModuleJob.run (file:REDACTED**)"]}

This is when I build this using esbuild and try to run it,

I have this piece of code that fails

import ValidatorJS from "validatorjs"; ValidatorJS.registerImplicit("notEmptyString", validateEmptyString, "The :attribute can not be empty string");

version - "3.22.1"

debugged the code and this this.messages[lang][attribute] = message;fails atthis.messages[lang] being undefined;

undefined ERROR Error: Cannot find module './lang/en' at

_load: function(lang) { if (!this.messages[lang]) { try { var rawMessages = require_method("./lang/" + lang); this._set(lang, rawMessages); } catch (e) { console.error(e, 'some error in load') - // this is where the error comes from } } },

this problem still persists in this library.
