Upload success with DO space but never show

I’m using DO space for the first time to upload images and documents. I used multer and multer-s3 to upload multiple images. The function works fine and show successful without error. But DO space doesn’t show any updates. The files doesn’t upload to the DO space. I tried URL but no such key.

I set my DO Space:

• Enable File Listing
• Enable CDN
• CORS: allow all the wildcard domain

const bucket = 'MY_DO_UNIQUE_NAME';
const spacesEndpoint = new AWS.Endpoint('sgp1.digitaloceanspaces.com');
const s3 = new AWS.S3({
        endpoint: spacesEndpoint,
        accessKeyId: process.env.DO_ACCESS_KEY,
        secretAccessKey: process.env.DO_SECRET_KEY
 });

const upload = multer({
      storage: multerS3({
        s3:s3,
        bucket: bucket,
        acl: 'public-read',
        key: function (request, file, cb) {
          console.log(file);
          cb(null, file.originalname);
        }
      }),

}).array('file', 100);

upload(req, res, function (error, file, data) {
          if (error) {
            console.log(error);
            return response.redirect("/error");
          }
          console.log('File uploaded successfully.');
});
