Thanks Matt.
I was looking into the json file and at the end I found the following
{"attributes":{"description":"Filebeat Icinga module dashboard for the main log files","hits":0,"kibanaSavedObjectMeta":{"searchSourceJSON":"{"query":{"language":"kuery","query":""},"version":true,"filter":,"highlightAll":true}"},"optionsJSON":"{"darkTheme": false}","panelsJSON":"[{"panelIndex":"1","panelRefName":"panel_0","version":"7.3.0","gridData":{"x":24,"y":0,"w":24,"h":12,"i":"1"},"embeddableConfig":{}},{"panelIndex":"2","panelRefName":"panel_1","version":"7.3.0","gridData":{"x":0,"y":12,"w":48,"h":100,"i":"2"},"embeddableConfig":{"columns":["icinga.main.facility","log.level","message"],"sort":["@timestamp","desc"]}},{"panelIndex":"3","panelRefName":"panel_2","version":"7.3.0","gridData":{"x":0,"y":0,"w":24,"h":12,"i":"3"},"embeddableConfig":{}}]","timeRestore":false,"title":"[Filebeat Icinga] Main Log ECS","version":1},"id":"f693d260-2417-11e7-a83b-d5f4cebac9ff-ecs","migrationVersion":{"dashboard":"7.3.0"},"references":[{"id":"d8e5dc40-2417-11e7-a83b-d5f4cebac9ff-ecs","name":"panel_0","type":"visualization"},{"id":"ffaf5a30-2413-11e7-a0d9-39604d45ca7f-ecs","name":"panel_1","type":"search"},{"id":"2cf77780-2418-11e7-a83b-d5f4cebac9ff-ecs","name":"panel_2","type":"visualization"}],"type":"dashboard","updated_at":"2020-11-16T09:18:30.348Z","version":"WzIxOCwxXQ=="}
{"exportedCount":465,"missingRefCount":1,"missingReferences":[{"id":"674c44c0-1a8b-11eb-90aa-4f76e942edde","type":"visualization"}]}
Then I searched for that Id and it's in the file .....so should I remove that line then the json will be fine to be imported?
Thanks Matt
