grafana_contact_point resource not working with sns

[FloSch96]

Terraform Version

1.7

Terraform Grafana Provider Version

3.24.0

Grafana Version

11.5.1

Affected Resource(s)

Creating a grafana_contact_point resource gives me the following error:
╷
│ Error: [POST /v1/provisioning/contact-points][400] postContactpointsBadRequest {"message":"invalid object specification: failed to validate integration "Alerts SNS Terraform" (UID ) of type "sns": must specify topicArn, targetArn, or phone number"}
│
│ with grafana_contact_point.grafana_sns_alarm_endpoint,
│ on main.tf line 21, in resource "grafana_contact_point" "grafana_sns_alarm_endpoint":
│ 21: resource "grafana_contact_point" "grafana_sns_alarm_endpoint" {
│
╵

As much as I saw in the documentation, there is no valid "topicArn" or "targetArn" field

I also tried to hardcode everything already without environment variables, but the error stays the same
