S3 File Sever doesn't work saves files to mongod

#1 
const S3Adapter = require('@parse/s3-files-adapter');
const s3Adapter = new S3Adapter({
  bucket: "my_bucket",
  directAccess: true,
  baseUrl: " https://buckeet.s3.us-west-004.backblazeb2.com", 
  baseUrlDirect: false,
  signatureVersion: 'v4',
  globalCacheControl: 'public, max-age=86400',
  region: 'us-west-004',
  s3overrides: {
    endpoint: "s3.us-west-004.backblazeb2.com", 
    accessKeyId: "xxxxxxxxxxxxxxxxxxxxxxx",
    secretAccessKey: "xxxxxxxxxxxxxxxxxxxxxxx"
  },
});

and then

config = {
appName: ...
.. 
  filesAdapter:s3Adapter
}

but it doesn’t save in my s3 bucket.
