Ember+ plugin for zabbix7 times out when requesting specific inner most elements in the ember tree. Some elements work without issue, others always time out. I have not been able to identify why some elements consistently fail and others don't.

For instance: ptp -> config -> slave_only works without issue:

zabbix_agent2 -t "ember.get[redacted:9000,1.1.3]"
ember.get[redacted:9000,1.1.3]             [s|{"1.1.3":{"path":"1.1.3","element_type":"qualified_parameter","value":true}}]

However, ptp -> status -> ports -> ra0 ->grandmaster_id fails

zabbix_agent2 -t "ember.get[redacted:9000,1.0.1.0.0.3]"
ember.get[redacted:9000,1.0.1.0.0.3]       [m|ZBX_NOTSUPPORTED] [Failed to execute handler: handler failed: failed to handle request: failed to find element, err Failed to find Ember+ response in time.: element not found.]

I have tested plugins versions 7.2.6, 7.2.7rc1 and 7.4.0beta2. Same behaviour on all versions.

I am not sure if this is a bug in the plugin or a limitation in the ember protocol. From the Windows Ember Viewer there seems to be no difference between the elements that the Zabbix ember+ plugin can fetch and those that it can not.
