Causes
The Content-Encoding field in the request contains invalid characters, such as \r (carriage return) or \n (newline).
Examples
For example, if you use a PostObject request to upload an object and set the Content-Encoding form field to declare the encoding format, the request fails if the field value contains \r or \n.
Solutions
Remove any invalid characters from the Content-Encoding value before submitting the request.
