[Bug]: "Provider produced inconsistent result after apply" in aws_cognito_user_pool_client

[MrBuddyCasino]

Terraform Core Version

1.1.7

AWS Provider Version

~> 4.55

Affected Resource(s)

• module.cognito_oauth.aws_cognito_user_pool_client

Expected Behavior

apply should have succeeded

Actual Behavior

Terraform output the error message provided below. It looks like an "empty list vs null" issue.

Relevant Error/Panic Output Snippet

│ Error: Provider produced inconsistent result after apply
│ 
│ When applying changes to
│ module.cognito_oauth.aws_cognito_user_pool_client.this["connectservices-oauth-dev"],
│ provider "provider[\"registry.terraform.io/hashicorp/aws\"]" produced an
│ unexpected new value: .logout_urls: was cty.SetValEmpty(cty.String), but
│ now null.
│ 
│ This is a bug in the provider, which should be reported in the provider's
│ own issue tracker.

Terraform Configuration Files

resource "aws_cognito_user_pool_client" "this" {
  for_each = var.pool_clients

  name         = each.key
  user_pool_id = aws_cognito_user_pool.this.id

  generate_secret       = true
  access_token_validity = 60

  allowed_oauth_flows = [
    "code",
  ]
  allowed_oauth_flows_user_pool_client = true
  allowed_oauth_scopes = [
    "email",
    "openid",
  ]

  callback_urls = each.value.callback_urls
  logout_urls   = []

  enable_propagate_additional_user_context_data = false

  enable_token_revocation = true
  id_token_validity       = 60

  token_validity_units {
    access_token  = "minutes"
    id_token      = "minutes"
    refresh_token = "days"
  }

  explicit_auth_flows = [
    "ALLOW_REFRESH_TOKEN_AUTH",
    "ALLOW_USER_PASSWORD_AUTH",
    "ALLOW_USER_SRP_AUTH",
  ]

  prevent_user_existence_errors = "ENABLED"

  read_attributes = [
    "email",
    "email_verified",
  ]
  write_attributes = [
    "email",
  ]

  supported_identity_providers = [
    aws_cognito_identity_provider.this.provider_name,
  ]
}

Steps to Reproduce

I'm not sure it is feasible to reproduce a full Cognito setup. The "null vs empty list" issue can probably easily be checked in the backing code.

Seeing same, provider update to 4.60 broke compatibility for all existing Cognito clients, giving unexpected new value error for attributes
.allowed_oauth_flows
.callback_urls
.logout_urls
.supported_identity_providers

Checked, downgrading to 4.59 allows to apply with no error
terraform { required_providers { aws = { source = "hashicorp/aws" version = "<= 4.59" } } }

Worked for me forcing provider <= 4.59 as @alnemo mentioned

[half2me]

same issue here when I have:

explicit_auth_flows = []

[sherifkayad]

I have the same issue when I have empty callback URLs e.g.:

callback_urls = []

Hi, it still seems to give an error. I am using tf core 1.4.2 and aws provider 4.62.0.
I've also tried other combinations (upgraded to aws provider 4.63.0, downgraded tf core), but it still gives me:

│ Error: Provider produced inconsistent result after apply │ │ When applying changes to aws_cognito_user_pool_client.my_ui, provider │ "provider[\"registry.terraform.io/hashicorp/aws\"]" produced an unexpected │ new value: .token_validity_units: block count changed from 0 to 1. │ │ This is a bug in the provider, which should be reported in the provider's │ own issue tracker. ╵

Anything I could try? Downgrading aws provider to 4.59.0 does not show this issue.
