Problems when integrate the S3 on project Symfony 5.1

[andreguipeil]

Hello!
I receive a error when I was integrating the Gaufrette with S3 adapter, the error is:

You have requested a non-existent parameter "knp_gaufrette.stream_wrapper.protocol".

My config is:

knp_gaufrette:
  adapters:
    cavb_images_adapter:
      aws_s3:
        service_id: 'acme.aws_s3.client'
        bucket_name: ''%env(AWS_BUCKET)%''
        detect_content_type: true
  stream_wrapper: ~
  filesystems:
    cavb_images_fs:
      adapter: cavb_images_adapter

I'm installed VichImage and php-sdk to adapt to S3 but I receive this error and I don't know what I need to do.

My symfony version is: 5.1

Hey,
I suppose that this is already sufficient:

knp_gaufrette:
    stream_wrapper: ~
    ...

See https://github.com/dustin10/VichUploaderBundle/blob/master/docs/storage/gaufrette.md

In my case problem was in vich config filename extension. Symfony 5.1 default kernel code loads only yaml, not yml.

This is probably caused by lack of proper credentials set on s3 client. Make sure you include credentials in your s3 client and that your credentials user have right permissions.
