What is this content unknown, key unknown ? does it serve any purpose ?

[Mgrdich]

it is related to the message interface where the type if it is being send from the BE

/**
     * 
     * @type {MessageFormat}
     * @memberof TopicMessage
     */
    keyFormat?: MessageFormat;
    /**
     * 
     * @type {MessageFormat}
     * @memberof TopicMessage
     */
    valueFormat?: MessageFormat;

/**
 * 
 * @export
 * @enum {string}
 */
export enum MessageFormat {
    AVRO = 'AVRO',
    JSON = 'JSON',
    PROTOBUF = 'PROTOBUF',
    UNKNOWN = 'UNKNOWN'
}
