Javascript AWS.405'；方法不允许'；

我正在尝试使用AWS。理解 但是保持get405“不允许使用方法” 我不确定这是授权问题还是其他问题。 请你帮我找出哪里出了问题，好吗

  const comprehend = sentence => (new Promise((resolve, reject) => {
    const comprehend = new AWS.Comprehend({
      accessKeyId: process.env.AWSAccessKeyId,
      secretAccessKey: process.env.AWSSecretKey,
      region: 'eu-central-1', // EU (Frankfurt)
      endpoint: 'https://rds.eu-central-1.amazonaws.com',
      apiVersion: '2017-11-27',
    });
    comprehend.batchDetectEntities({
      LanguageCode: 'en',
      TextList: sentence.match(/[\w\W\s\n.]{0,4999}/g),
    }, (error, data) => {
      console.log(error, data);
      if (error) return reject(error);
      return resolve(data);
    });
  }));

结果是

向您致以最良好的问候。Anton。

我使用相同的凭据运行aws config cli命令，问题以某种方式得到解决
