Critical I have an issue where running a discovery is failing. This has been working for years. When looking at the host configuration > discovery there is the red "!" and it says "Value should be a JSON object." Every server, new or old, is now failing where it used to work.
Our script or agent config hasn't changed. I have recently updated the server and all proxies to 3.4.7. The discovery items are working on servers running under the one proxy that is still on 3.4.7.
This is an example of the discovery that shows as failed from a 3.4.7 proxy:
[root@zbx-prx-ugw01 externalscripts]# zabbix_proxy --version
zabbix_proxy (Zabbix) 3.4.7
