In dashboard A
I have a templated variable called region with datasource Influxdb.
It has values like “EAST”, “WEST”.
I defined it should also have an All option (checked Include All option).
The variable is passed inside a link to another dashboard B:
var-region_name=${region_name}
The same region variable is defined in Dashboard B.
When the user selects in Dashboard A the region as All option and in turn clicks to open dashboard B,
the region shows as {EAST,WEST} in dashboard B instead the desired value All.
This in turn causes the query to have an empty result.
To fix the user has to select the All option in dashboard B which is obviously not user-friendly.
How can I see that All passes as All from dashboard to dashboard.
