HTTP status code 404 is used if creation of public IP fails

[flobeier]

Description

│ Error: Error creating public IP
│ 
│   with stackit_public_ip.vpn_gateway,
│   on stackit.tf line 106, in resource "stackit_public_ip" "vpn_gateway":
│  106: resource "stackit_public_ip" "vpn_gateway" {
│ 
│ Calling API: 404 Not Found, status code 404, Body: {"code":404,"msg":"External network xxxx-xxxx-xxxx-xxxx-xxxx is not reachable from subnet xxxx-xxxx-xxxx-xxxx-xxxx.  Therefore, cannot associate Port xxxx-xxxx-xxxx-xxxx-xxxx with a Floating IP."}

HTTP status code 404 is used for the error, I think it should be 400 instead.

Steps to reproduce

Not sure at this point, I just want to report the issue with the API.

Actual behavior

Error is reported with HTTP status code 404 (Not Found).

Expected behavior

Error is reported with HTTP status code 400 (Bad Request).

Environment

• OS: Ubuntu 25.04
• Terraform version (see terraform --version): v1.12.1
• Version of the STACKIT Terraform provider: v0.56.0
