HI, there.

I'm trying to create an alert on MongoDB Atlas with terraform, but I´m getting the error below:

mongodbatlas_alert_configuration.default: Creating...

Error: The terraform-provider-mongodbatlas_v1.11.0 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

Thanks for opening this issue. The ticket INTMDB-1017 was created for internal tracking.

Hello @Kikivsantos
Thanks for opening the issue. I was able to reproduce the issue and the fix will be available in 1.11.1. In the meantime, the workaround is to remove matcher, metric_threshold_config and threshold_config from your configuration since all theirs fields are null.

resource "mongodbatlas_project" "atlas-project" {
  name   = "TESTProj"
  org_id = "60ddf55c27a5a20955a707d7"
}

resource "mongodbatlas_alert_configuration" "default" {
  project_id = mongodbatlas_project.atlas-project.id
  event_type = "CLUSTER_MONGOS_IS_MISSING"
  enabled    = false

  notification {
    type_name     = "GROUP"
    interval_min  = 60
    delay_min     = 0
    sms_enabled   = false
    email_enabled = true
    roles         = ["GROUP_OWNER"]
    api_token     = ""
  }
}

Thanks

Hello @Kikivsantos,
We released v1.11.1. Feel free to reopen the issue if you are still facing the same problem with v1.11.1.

Thanks

Thank you, @andreaangiolillo

Now it worked to create the alerts.
