[jmperez81]

Expected Behavior

Actual Behavior

Terraform Version

Terraform v1.14.6
on darwin_arm64

• provider registry.terraform.io/integrations/github v6.11.1

Affected Resource(s)

• github_repository

Terraform Configuration Files

terraform {
  required_providers {
    github = {
      source  = "integrations/github"
      version = "~> 6.0"
    }
  }
}

provider "github" {
  # token = var.github_token  # or set GITHUB_TOKEN env var
  # owner = var.owner         # or set GITHUB_OWNER env var
}

resource "github_repository" "example" {
  name        = "my-test-repo"
  description = "Some description"
  visibility  = "public"
}

Steps to Reproduce

1. terraform apply number 1 --> repository is created
2. Remove description line from resource definition
3. terraform apply number 2 --> repository description is removed from repository

Debug Output

$ terraform apply
github_repository.example: Refreshing state... [id=my-test-repo]

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  ~ update in-place

Terraform will perform the following actions:

  # github_repository.example will be updated in-place
  ~ resource "github_repository" "example" {
      - description                             = "Some description" -> null
        id                                      = "my-test-repo"
        name                                    = "my-test-repo"
        # (39 unchanged attributes hidden)

        # (1 unchanged block hidden)
    }

Plan: 0 to add, 1 to change, 0 to destroy.

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.

  Enter a value: yes

github_repository.example: Modifying... [id=my-test-repo]
github_repository.example: Modifications complete after 2s [id=my-test-repo]

This is normal Terraform behaviour, if you modify a resource and don't use ignore_changes, then it will apply your changes
