It seems like self::getIdentifierFromXML($xml) can also be of type null; however, parameter $identifier of SimpleSAML\SAML2\XML\samlp\ManageNameIDRequest::__construct() does only seem to accept SimpleSAML\SAML2\XML\saml\EncryptedID|SimpleSAML\SAML2\XML\saml\NameID, maybe add an additional type check?
