PagerDuty returned a non-JSON object.

[Shaman0S]

Have setup integration in accordance https://www.zabbix.com/integrations/pagerduty
Have checked Action log.
It shows failed actions with error "PagerDuty notification failed : incorrect response. PagerDuty returned a non-JSON object."
Same error in zabbix_server.log

Please help to troubleshoot further.

So the issue is with template.
https://git.zabbix.com/projects/ZBX/...erduty.yaml#12

Seems to be fixed in ZBXNEXT-9809

Feel free to update relevant template for media type.
