Error deleting azure resource....Failure sending request: StatusCode=400

Terraform
1

Hi,
I am seeing some inconsistent behavior while deleting azure resource as part of terraform destroy plan. Most of the resources deleted successfully but some like - Network security group or network interface cannot be deleted in 1st run. So as a work around i am running the destroy again to delete the remaining resources. Do i need to follow any sequence while destroying the resources? What is the meaning of this error and how to resolve this?

Error: Error deleting Network Security Group “devNSG” (Resource Group “TerraAzure”): network.SecurityGroupsClient#Delete: Failure sending request: StatusCode=400 – Original Error: Code=“NetworkSecurityGroupOldReferencesNotCleanedUp” Message=“Network security group devNSG cannot be deleted because old references for the following Nics: (…/devNIC) and Subnet: (…/devNSG:) have not been released yet.” Details=

I don’t see this type of issue though while deleting AWS resources.

Any help would be highly appreciated.
Thank you.

Hi

I have the exact same problem. All resources are not being deleted the first time around and the OS disk doesn’t get deleted at all.
