Presigned URLs can not have expires_in: option of more than a week.

The limit is set in aws-sdk-core/s3/presigner.rb.

To me this limit seems somewhat random as it is also not explained in the documentation or comments. Is that a limit set by the Amazon API? If it is, why is it handled in the presigner explicitly instead of using the failed request? If it is not, why is it enforced in the presigner?

This is a limitation of sigv4 presigned URLs. It is handled in the presigned as the error messages received from the api can be hard to decipher and frequently are consumed by users that did not generate the url.

The presigner enforces the limit because that sigv4 limitation would otherwise cause errors (you could see this if you tried to manually generate a presigned request with a different limit.
