Hi, getting this error on Grafana table panel.
431 Request Header Fields Too Large

This was working before, I don’t think anything changed.
I have other Grafana dashboards using the same Influx server without a problem.
Grafana v7.4.0 , InfluxDB shell version: 1.8.1
The issue is with the Variable VMName. I have setup show tag values with key =“VMName” in the variable setup, i have multi-value and include all options enabled. The preview seems to work.
When I use the ALL drop down from the panel, it bombs out with the error.
query looks like this:
SELECT last(“CPU”), “MemoryGB”, “ProvisionedSpaceGB” FROM “VMInfo” WHERE (“ClientName” =~ /^$ClientName$/ AND “VCenterName” =~ /^$VCenterName$/ AND “Clustername” =~ /^$Clustername$/ AND “VMName” =~ /^$VMName$/ AND “OSFullName” =~ /^$OSFullName$/ AND “PowerState” =~ /^$PowerState$/ AND “CIStatusVM” =~ /^$CIStatusVM$/) AND $timeFilter GROUP BY “ClientName”, “VCenterName”, “Clustername”, “VMName”, “OSFullName”, “PowerState”, “CIStatusVM”
Info about the VMInfo tag:
show tag values cardinality with key =“VMName”
name: VMInfo
count
43049
thanks
