node.js - Mailgun-401禁止

Question

我尝试使用mailgun发送电子邮件。我使用node.js(nest.js)，这是我的邮件服务。我应该改变什么？当我尝试发送第一封电子邮件(mailgun官方网站中的描述)时，我收到了相同的错误消息。

import { Injectable } from '@nestjs/common';
import * as Mailgun from 'mailgun-js';
import { IMailGunData } from './interfaces/mail.interface';
import { ConfigService } from '../config/config.service';

@Injectable()
export class MailService {
  private mg: Mailgun.Mailgun;

  constructor(private readonly configService: ConfigService) {
    this.mg = Mailgun({
      apiKey: this.configService.get('MAILGUN_API_KEY'),
      domain: this.configService.get('MAILGUN_API_DOMAIN'),
    });
  }

  send(data: IMailGunData): Promise<Mailgun.messages.SendResponse> {
    console.log(data);
    console.log(this.mg);
    return new Promise((res, rej) => {
      this.mg.messages().send(data, function (error, body) {
        if (error) {
          console.log(error);
          rej(error);
        }
        res(body);
      });
    });
  }
}

当我尝试发送消息时，出现禁止说明的401错误。
我的毫克(console.log(this.mg))

Mailgun {
  username: 'api',
  apiKey: '920d6161ca860e7b84d9de75e14exxx-xxx-xxx',
  publicApiKey: undefined,
  domain: 'lokalne-dobrodziejstwa.pl',
  auth: 'api:920d6161ca860e7b84d9de75e14exxx-xxx-xxx',
  mute: false,
  timeout: undefined,
  host: 'api.mailgun.net',
  endpoint: '/v3',
  protocol: 'https:',

  options: {

    proxy: undefined,
    timeout: undefined,
    retry: 1,
    testMode: undefined,
    testModeLogger: undefined
  },
  mailgunTokens: {}
}

我的邮件正文

{
  from: 'rejestracja@lokalne-dobrodziejstwa.pl',
  to: 'me@gmail.com',
  subject: 'Verify User',
  html: '\n' +
    '                <h3>Hello me@gmail.com!</h3>\n' +
    '            '
}

当我的域名位于欧盟区域时，我遇到了这个问题。使用EU区域时，必须在配置中指定它-Mailgun对此没有明确说明。
所以会是这样的:

var mailgun = require("mailgun-js")({
  apiKey: API_KEY,
  domain: DOMAIN,
  host: "api.eu.mailgun.net",
});
