}

Debug Output

NA

Panic Output

NA

Expected Behavior

Have the same uid (JOUdHGZZz) on Grafana, so URL should be:
https://abc.company.com/d/JOUdHGZZz/my-dashboard

Actual Behavior

Grafana shows different uid, the dashboard URL is:
https://abc.company.com/d/dlhHPsFGk/my-dashboard

From Grafana documentation "If the dashboard in the json file contains an uid, Grafana will force insert/update on that uid". So, this mean that somehow Terraform is not sending the uid that I add on tpl (json).

From terraform-provider-grafana (here) I see that on function prepareDashboardModel both, id and uid, are being removed from json before sending this data to Grafana. This justifies why Grafana is creating new uid..

func prepareDashboardModel(configJSON string) map[string]interface{} {
	configMap := map[string]interface{}{}
	err := json.Unmarshal([]byte(configJSON), &configMap)
	if err != nil {
		// The validate function should've taken care of this.
		panic(fmt.Errorf("Invalid JSON got into prepare func"))
	}

	delete(configMap, "id")
	// Only exists in 5.0+
	delete(configMap, "uid")
	configMap["version"] = 0

	return configMap
}

Is there any reason why uid is being removed?

uid is being used for Grafana to build the URL.. any other alternatives?

Steps to Reproduce

Send uid on json

I'm facing same issue also, it's something basic, I can't link one dashboard with another because of this.
