translations does not work in DTO's

[allanojeda]

Currently I'm having issues trying to translate the class-validators errors in a DTO. I set up main.ts, and dto as documented.

Main:

app.use(I18nMiddleware);
  app.useGlobalPipes(new ValidationPipe({ transform: true }));
  app.useGlobalPipes(new I18nValidationPipe());

  app.useGlobalFilters(
    new I18nValidationExceptionFilter({
    }),
  );

dto:

export class LoginDto {
  @IsEmail(
    {},
    {
      message: i18nValidationMessage('validation.validateEmail'),
    },
  )
  email: string;

  @IsString({
    message: i18nValidationMessage('validation.password'),
  })
  @Length(1, 18)
  password: string;
}

app.module: I18nModule.forRoot({ fallbackLanguage: 'en', loaderOptions: { path: join(__dirname, '/langs/'), watch: true, }, resolvers: [new HeaderResolver(['lang']), AcceptLanguageResolver], }),

the langs folder has this type of structure:

/langs/en/validation.json

{"password": "Password should be string"
}

I'm not using graphql, and the response I get after trying to see the errors translation for a bad input:

{
    "statusCode": 400,
    "message": [
        "password must be longer than or equal to 1 and shorter than or equal to 18 characters",
        "validation.password|{\"value\":123}"
    ],
    "error": "Bad Request"
}

As seen, I am not able to get the translation of validation.password key. Im not sure whats wrong, because I am able to translate custom messages in my services using I18nService. I'm using node v16.14.1 with NestJS framework.

Remove the code that instantiates validation pipe. You can pass the same options (except exceptionFactory) to I18nValidationPipe.

  app.useGlobalPipes(new I18nValidationPipe({ transform: true}));
  app.useGlobalFilters(
    new I18nValidationExceptionFilter({
    }),
  );
