Is Json format error?

grafana send this content use webhook:
‘{“evalMatches”:[],“ruleId”:1,“ruleName”:“Query Durations alert”,“ruleUrl”:"http://localhost:3000/d/MK-yT_wiz/prometheus-2-0-stats?fullscreen’:
‘true\u0026edit=true\u0026tab=alert\u0026panelId=38\u0026orgId=1",“state”:“ok”,“title”:"[OK] Query Durations alert"}’

is a wrong json?

grafana v5.3.4

looks ok, we have no one else reporting issue with invalid json. How are you deserializing it?

sorry,it’s my careless
