Data Transfers · Problems and messages
Why did my transfer fail with “the S3 bucket couldn't be found”?
Short answer: The path didn't start with a bucket that exists on that account. Edit the account under More → Connect Accounts…, set its Bucket field to your real bucket name, and run the transfer again.
On a bucket account, the first part of the destination path has to be the bucket's name. The transfer was sent to a bucket that doesn't exist on that account — usually because the path didn't start with the bucket, or the name is spelled differently (bucket names are lower-case).
The message shows the name it tried. To fix it, open the account's settings under More → Connect Accounts…, choose Edit, set the Bucket field to your real bucket name, and run the transfer again; Storage Studio then adds the bucket to every path for you.
