i18nValidationMessage does not work correctly

[EizFeren]

Describe the bug

I've got very strange bug with some of class-validator identifiers - i18nValidationMessage does not translate message for them. All setup except details is same as described in quickstart guide.

Here's my setup to reproduce.

DTO with decorators:

import { Type } from 'class-transformer';
import { IsInt, Min } from 'class-validator';
import { i18nValidationMessage } from 'nestjs-i18n';

export class someDto {
  @Type(() => Number)
  @IsInt({
    message: i18nValidationMessage('validation.id.int'),
  })
  @Min(1, {
    message: i18nValidationMessage('validation.id.min'),
  })
  id: number;
}

validation.id.int and validation.id.min are simple strings, Id should be integer number and Id should be positive.

Actual result I have with this setup:

{
  message: [
    'validation.id.min|{"value":null,"constraints":[1]}',
    'validation.id.int|{"value":null}'
  ],
  error: 'Bad Request',
  statusCode: 400
}

I've tried some antoher decorators, such as IsNotEmpty, IsEmail, IsStrongPassword, and translation for them is working correctly. Also I've done some check for this case with I18nService - it translates validation.id.int and validation.id.min correctly.

Try this https://github.com/toonvanstrijp/nestjs-i18n/tree/main/samples/dto-validation. Also show your i18n files.
Have a hunch it might be due to the way you have nested the i18nValidationMessage key

Looks like problem is with testing environment. Idk how it can relate, but in fact - I tested this setup with live app, and error messages were translated correctly.

Then I've launched exact same code with supertest - and got bugged error messages. Perharps all another error messages with supertest were ok, except these for id check

In main.ts you should use I18ValidationPipe() instead of ValidationPipe()
You can pass the same options in both cases.

import { ValidationPipe } from '@nestjs/common';
app.useGlobalPipes(new ValidationPipe());

If I remove these lines my application runs successfully. I wasted my time on this. 😡
