我有以下代码：

const { S3Client } = require('@aws-sdk/client-s3');
const { createPresignedPost } = require('@aws-sdk/s3-presigned-post');

router.post(

    const { name, type } = req.body;
    const client = new S3Client({
      region: 'eu-central-1',
      credentials: {
        accessKeyId: process.env.AWS_ACCESS_KEY_ID,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
      },
    });
    const params = {
      Bucket: process.env.S3_BUCKET_NAME,
      Expires: 60,
      Conditions: [
        ['content-length-range', 100, 5242880],
        { 'Content-Type': 'image/jpeg' },
      ],
      Fields: {
        key: `blog/${name}`,
        'Content-Type': type,
        success_action_status: '201',
      },
    };
    try {
      const data = await createPresignedPost(client, params);
      return …
