When attempting to execute terraform destroy in the "Para Disésys" project within OpenStack, an error occurs due to special characters in the project name. Specifically, the presence of the accented character "é" in the project name leads to a UnicodeDecodeError during the deletion process, resulting in a 500 error response instead of the expected 404 response. This issue prevents Terraform from successfully destroying resources that have already been manually deleted from the OpenStack dashboard.
The specific error returned by OpenStack is:
{"computeFault": {"code": 500, "message": "The server has either erred or is incapable of performing the requested operation."}}
Upon investigating the Nova API logs, we observed the following traceback:
nova-api-osapi-76d4466df7-cqqc2 nova-osapi 2024-05-16 13:46:58.408 1 ERROR nova.api.openstack response = req.get_response(self._app)

This error occurs because the project name contains a special character (é), causing the UTF-8 decoding process to fail. However, the root issue is that Terraform attempts to delete a VM that no longer exists, and the API does not handle this scenario gracefully.
Steps to Reproduce:
source keystonerc
export OS_PROJECT_NAME="Para Disésys"
openstack token issue
# replace with your token
export OS_TOKEN=""
curl -X DELETE https://nova.tytesnet.net/v2.1/6bbe727a7d524579a367d46af74087/servers/3842729c-ef45-49c9-ad81-88e8a91065989 -H "X-Auth-Token: $OS_TOKEN"
Expected Behavior:
Executing terraform destroy should return a 404 error when attempting to delete a resource that has already been manually deleted from the OpenStack dashboard, regardless of any special characters in the project name.
Actual Behavior:
The presence of special characters in the project name, such as "é" in "Para Disésys" leads to a UnicodeDecodeError during the deletion process, resulting in a 500 error response instead of the expected 404 response.
