i18nValidationErrorFactory INTERNAL SERVER ERROR

[Natchii59]

Hello, I just tested nestjs-i18n in my nestjs application with a GraphQL api. I would like to use it for DTO validations, to translate my messages.

I have this setup:

• app.module.ts

  I18nModule.forRoot({
  fallbackLanguage: 'en',
  loaderOptions: {
  path: join(__dirname, 'i18n'),
  watch: true
  },
  resolvers: [CookieResolver, AcceptLanguageResolver]
  }),

• main.ts

  app.useGlobalPipes(new I18nValidationPipe())
  app.useGlobalFilters(new I18nValidationExceptionFilter())

• create-user.input.ts

  @InputType()
  export class CreateUserInput {
  @Field(() => String, { description: 'Username of user' })
  @Matches(/^[a-z0-9_]{3,}$/, {
  message: i18nValidationMessage('validation.USERNAME_FORMAT', {
    lang: 'fr'
  })
  })
  @Transform(({ value }) => value.toLowerCase())
  username: User['username']
  
  @Field(() => String, { description: 'Password of user' })
  @Matches(/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*\W).{12,}$/, {
  message: i18nValidationMessage('validation.PASSWORD_FORMAT')
  })
  password: User['password']
  }

When the validations are bad, I get this error.

the same problem

Got the same if I don't add the ValidationPipe to the global:

app.useGlobalPipes(
    new ValidationPipe(),
    new I18nValidationPipe({ transform: true }),
  )

but still couldn't make the translation work with DTO

I think I have more to do with graphql, but maybe you can help?

[rubiin]

If you could provide me a repro. The exception filter is meant to be used with HTTP as far as I know.

[stigmat4j]

no, there is support for graphql. Errors are even translated
