[Grafana] Problem using templates for Slack alerts

Monitoring and Observability Grafana
1

Sorry if i bother but im having problem using templates for slack alert:

	[{{- .Status | toUpper -}}{{- if eq .Status "firing" }} x {{ .Alerts.Firing | len -}}{{- end }}  | {{ .CommonLabels.env | toUpper -}} ] ||  {{ .CommonLabels.alertname -}}
{{- end -}}```
if create this template, i should be able to have a template "slack.title" for the slack contactpoint:
`title: "{{ template `slack.title` . }}"`  but instead i receive this error when applying with yaml:
`template "slack.title" not defined`  someone knows what am i doing wrong?

Did you add the slack template in the contact points tab?
my template is called “slack” and contains my go template with both title and message templates

Yep. i add there a template called slack (as the slack page says) but the error i receive in helm is what i wrote up there
