I'm looking to set up a transfer job to take files stored within an S3 bucket and load them to a GCS bucket. The credentials that I have give me access to the folder that contains the files that I need from S3 but not to the higher level folders.

When I try to set up the transfer job with the S3 bucket name under 'Amazon S3 bucket' and the access key ID & secret access key filled-in, the access is denied as you would expect given the limits of my credentials. However, access is *still* denied if I add the extra path information as a Prefix item (e.g. 'Production/FTP/CompanyName') and I do have access to this folder.

It seems as though I can't get past the fact that I do not have access to the root directory. Is there any way around this?
