Cannot destructure property 'templateName' of 'precompile(...)'

[hddananjaya]

Hi all, 🦄

Config:

    "@nestjs-modules/mailer": "^1.6.0",
    "nodemailer": "^6.5.0",
    "handlebars": "^4.7.7",

I'm trying to use with handlebars.

App Module:

@Module({
  imports: [
    UserModule,
    AdminModule,
    HotelModule,
    TypeOrmModule.forRoot(),
    ConfigModule.forRoot({ isGlobal: true }),
    MailerModule.forRootAsync({
      useFactory: () => ({
        transport:
          'smtps://no-reply@XXX:XXX@XXX.com',
        defaults: {
          from: '"XXX" <no-reply@XXX.com>',
        },
        template: {
          dir: path.resolve(__dirname, 'templates'),
          adapter: new HandlebarsAdapter(),
          options: {
            strict: true,
          },
        },
      }),
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})

Service:

import { Injectable } from '@nestjs/common';
import { MailerService } from '@nestjs-modules/mailer';

@Injectable()
export class UserMailService {
  constructor(private readonly mailerService: MailerService) {}

  sendEmailConfirmation(): void {
    this.mailerService
      .sendMail({
        to: 'test@nestjs.com',
        from: 'noreply@nestjs.com',
        subject: 'Testing Nest Mailermodule with template ✔',
        template: '/welcome',
      })
      .then((success) => {
        console.log(success);
      })
      .catch((err) => {
        console.log(err);
      });
  }
}

I get this error when I use templates.

TypeError: Cannot destructure property 'templateName' of 'precompile(...)' as it is undefined.

I manually copied templates folder to dist to check whether the problem is with paths. But it asks for templateName which I didn't provide.

Thanks!

Hi @hddananjaya put "./" before template value

.sendMail({
    to: 'test@nestjs.com',
    from: 'noreply@nestjs.com',
    subject: 'Testing Nest Mailermodule with template'
    template: './welcome',
})
