Can we have some context? ☺️

This issue occurs in the context of AWS S3. When a user provides a pre-signed URL that uses X-Amz-* query parameters for authentication while building proxies, AWS returns the error: "Only one authentication mechanism is allowed." This happens because, even when overridden in ProxyConfiguration, an empty string is still passed in the Authorization header.

To fix this, users can now set the flag includeAuthentication: false, ensuring the Authorization header is completely omitted.
