Alert rule templates: reReplaceAll after urlquery

[day4me]

Hi, guys. I'm trying to replace "+" with "%20" because urlquery function in go templates replaces space with "+".
So I'm doing something like this:
{{ urlquery .Labels.alertname | reReplaceAll "+" "%20" }}
Also tried {{ .Labels.alertname | urlquery | reReplaceAll "+" "%20" }} and it just does not work.
But works like this tho:
{{ reReplaceAll "+" "%20" .Labels.alertname | urlquery }}

If anyone knows how to make it work or maybe knows some workaround for space replacement with +, please help.)

I found the fix for this: I had to escape "+" symbol for reReplaceAll function. So it works like this {{ urlquery .Labels.alertname | reReplaceAll "\\+" "%20" }} .
