// this my config in app.module gateway

       I18nModule.forRoot({
            fallbackLanguage: "en",
            loaderOptions: {
                path: join(__dirname, "/i18n/"),

        }),

  app.connectMicroservice<MicroserviceOptions>(mainClientMicroservice(configService), { inheritAppConfig: true });

constructor(@Inject("somthing") private readonly client: ClientRMQ,) { }
    async getHello() {
        return await lastValueFrom<string>(this.client.send("hello", {}))
    }

and my microservice app:

@MessagePattern("hello")
    getHello(@I18n() i18n: I18nContext): string {
        return i18n.t("messages.hello")
    }

I use rabbitMq

I have the exact same issue. I thought I was executing code before the i18n module had loaded but if I manually hard code a language key into my code it works fine, so now I am passing the fallback language key as an environment variable as fallbackLanguage parameter is not working.
