Use Amazon CLI to upload files to an empty S3 Bucket | File transfer service configuration |Tealium Docs

When an S3 bucket is first created, it’s empty. If you try to access an empty S3 bucket, the following message may be displayed:

Failure to read attributes of ACCOUNT-PROFILE

Before uploading any CSV files, use the following aws s3api command to upload a file into the empty bucket:

aws s3api put-object --bucket <bucket> --key <key> --body <body>

The bucket value is the region domain in the format collect-REGION.tealium.com.
The key value specifies the filename you want to assign to the file, including the file prefix.
The body value specifies specifies the file location on the local system.

For example:

aws s3api put-object --bucket collect-us-east-1.tealium.com \
  --key bulk-downloader/ACCOUNT-PROFILE/test_fileimp_01.csv \
  --body ./test_fileimp_01.csv
