Am trying to load a modified json from kibana/7/dashboard/Winlogbeat.json as our Kibana instances are firewalled off for beats clients. So I'll have to import a version manually from my desktop, only Kibana complains.
Wouldn't the format of kibana/7/dashboard/Winlogbeat.json be right for importing?
If so what would I need to change to adapt to our custom named index [+pattern]?
