Problem description
The Expires field in the object metadata contains invalid characters.
Causes
The Expires field value includes control characters such as \r or \n, which are not permitted by RFC 2616.
Examples
A PostObject request sets the Expires field to specify a cache expiration time, for example, 2022-10-12T00:00:00.000Z. If that value contains \r or \n, the request fails with this error.
Solutions
Remove the invalid characters from the Expires field value. The value must conform to the HTTP-date format defined in RFC 2616.
