Hi All, I’ve updated aws iam user name to use controlled naming(https://www.pulumi.com/blog/infrastructure-as-code-resource-naming/#controlled-naming). Now while deleting the user resource, pulumi is still looking for the user with old name and is failing with No such entity error.

aws.iam.User(
            name=_user['name'], // Added this field to have the name field updated with name 'pulumi_sample_user'
            resource_name=_user['name'],
            path=_user['path'],
            tags=_user['tags']
        )
Error message: 
error removing IAM User (pulumi_sample_user) group memberships: Error removing user "pulumi_sample_user" from all groups: NoSuchEntity: The user with name pulumi_sample_user cannot be found

How to proceed?

Add alias? https://www.pulumi.com/docs/intro/concepts/resources/options/aliases/

Hi @high-grass-3103 I’m unable to delete resources even after addition of alias. May be i’m doing something wrong. Attaching the state file corresponding to this resource

{
  "urn": "urn:pulumi:dev::project::aws:iam/user:User::pulumi_de",
  "custom": true,
  "id": "pulumi_de-abc8bde",
  "type": "aws:iam/user:User",
  "inputs": {
    "__defaults": [
      "forceDestroy"
    ],
    "forceDestroy": false,
    "name": "pulumi_de_hello_world"
  },
  "outputs": {
    "arn": "arn:aws:iam::aws_account_no:user/pulumi_de_hello_world",
    "forceDestroy": false,
    "id": "pulumi_de_hello_world",
    "name": "pulumi_de_hello_world"
  },
  "parent": "urn:pulumi:dev::project::pulumi:pulumi:Stack::project-dev",
  "provider": "urn:pulumi:dev::project::pulumi:providers:aws::default_4_36_0::random_no",
  "propertyDependencies": {
    "name": null,
    "path": null,
    "tags": null
  },
  "aliases": [
    "urn:pulumi:dev::project::aws:iam/user:User::pulumi_de",
    "urn:pulumi:dev::project::aws:iam/user:User::pulumi_de_hello_world",
    "urn:pulumi:dev::project::aws:iam/user:User::pulumi_de-abc8bde"
  ],
  "sequenceNumber": 1
}

One thing that works here is manually changing the ID to

pulumi_de_hello_world

wanted to know if there are programmatic ways

Might have been easier if you posted the code before and after change

@high-grass-3103 adding code and stack states
