Hello,
I was using Grafana 5.4.3 and alias by $tag_ was working fine, but not anymore since I upgraded to 6.6.0.
It is now showing a “!” on top left of the chart with “n is not a function”,
when I edit this panel, it is working if I remove the alias by $tag_ but if I put it back it shows an error :
I also tried the [[tag_name]] syntaxe but still the same, did anybody encounter the same issue?
Thanks
