There is lack of configuration of "Binary" type of information during the Connector configuration: https://www.zabbix.com/documentation/7.0/en/manual/config/export/streaming#configuration and there is no "5 - binary" type visible in .ndjson file as it should be based on mention in the documentation https://www.zabbix.com/documentation/7.0/en/manual/appendix/protocols/real_time_export#item-values resulting in binary data not being exported.
