Description

  • We are using STACKIT Terraform provider version 0.115.0.
  • When we run terraform apply to create the mongodb flex instance we simply get 404 error with the message
    Calling API: 404 Not Found, status code 404, Body: {"message":"mongodb not │ found","code":404,"type":"NotFound"}
  • We also tried with version 0.114.0 and we received the same error message as above.

Steps to reproduce

  • Simply declare the MongoDB Flex instance in the terrafor code to create a new MongoFlex instance.
resource "stackit_mongodbflex_instance" "example" {
  project_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  name       = "example-instance"
  acl        = ["0.0.0.0/0"]
  flavor = {
    cpu = 1
    ram = 4
  }
  replicas = 1
  storage = {
    class = "premium-perf2-mongodb"
    size  = 10
  }
  version = "7.0"
  options = {
    type                       = "Single"
    snapshot_retention_days    = 3
    point_in_time_window_hours = 30
  }
  backup_schedule = "0 0 * * *"
}
  1. Run terraform apply
  2. It produces the issue.
 with stackit_mongodbflex_instance.mongodb-cluster (mongodb-cluster),
│   on cdk.tf.json line 132, in resource.stackit_mongodbflex_instance.mongodb-cluster (mongodb-cluster):
│  132:       }
│ 
│ Calling API: 404 Not Found, status code 404, Body: {"message":"mongodb not
│ found","code":404,"type":"NotFound"}
│ 
│ 
│ Trace ID: "8eb72ba607dc14ea50e36e259d23936c"

Actual behavior

  • The STACKIT API is returning 404 even for the API calls.

Expected behaviour

  • The stack creation should simply succeed with creation of MongoDB flex instance.

Environment

  • OS: MacOS/Linux
  • Terraform version (see terraform --version): v1.15.2
  • Version of the STACKIT Terraform provider: v0.115.0 & v.114.0 as well

Additional information

  • It worked perfectly fine until this Wednesday.

    Please also see audit log entry. Maybe it has a hint that an old route is being called.

    It seems that the bug is not in the terraform provider but more at the API level as we can reproduce the bug also on the portal.
