[BUG] Lex Bot Resource Creation/Update Fails with Provider State Inconsistency Error

Issue: Lex Bot Resource Creation/Update Fails with Provider State Inconsistency Error

Description

When creating or updating an awscc_lex_bot resource, the provider fails during terraform apply with a state inconsistency error related to the bot_locales attribute. The error occurs both during initial creation and subsequent updates of the bot but the bot is created successfully.

Community Note

• Please vote on this issue by adding a 👍 reaction to the original issue to help the community and maintainers prioritize this request

• If you are interested in working on this issue or have submitted a pull request, please leave a comment
• The resources and data sources in this provider are generated from the CloudFormation schema, so they can only support the actions that the underlying schema supports. For this reason submitted bugs should be limited to defects in the generation and runtime code of the provider. Customizing behavior of the resource, or noting a gap in behavior are not valid bugs and should be submitted as enhancements to AWS via the CloudFormation Open Coverage Roadmap.

Expected Behavior

1. Configure the AWSCC provider:

provider "awscc" {
  region = var.region
  assume_role = {
    role_arn = var.resource_role_arn
  }
}

2. Create a minimal Lex bot configuration:

resource "awscc_lex_bot" "demo_lexv2_bot" {
  name     = "botTest"
  role_arn = aws_iam_role.lex_role.arn
  data_privacy = {
    child_directed = false
  }
  idle_session_ttl_in_seconds = 300
  auto_build_bot_locales      = true
  bot_locales = [
    {
      locale_id                = "en_US"
      nlu_confidence_threshold = 0.7
      voice_settings = {
        engine   = "standard"
        voice_id = "Kevin"
      }
      intents = [
        {
          name = "Sales"
          sample_utterances = [
            {
              utterance = "sales"
            }
          ]
          dialog_code_hook = {
            enabled = false
          }
          fulfillment_code_hook = {
            enabled = false
          }
        },
        {
          name        = "FallbackIntent"
          description = "Default intent when no other intent matches"
          dialog_code_hook = {
            enabled = false
          }
          fulfillment_code_hook = {
            enabled = false
          }
          parent_intent_signature = "AMAZON.FallbackIntent"
        }
      ]
    }
  ]
}

3. Run terraform plan
4. Run terraform apply
5. Bot creation should complete successfully without errors.

Actual Behavior

Steps to Reproduce

1. Configure the AWSCC provider:

provider "awscc" {
  region = var.region
  assume_role = {
    role_arn = var.resource_role_arn
  }
}

2. Create a minimal Lex bot configuration:

resource "awscc_lex_bot" "demo_lexv2_bot" {
  name     = "botTest"
  role_arn = aws_iam_role.lex_role.arn
  data_privacy = {
    child_directed = false
  }
  idle_session_ttl_in_seconds = 300
  auto_build_bot_locales      = true
  bot_locales = [
    {
      locale_id                = "en_US"
      nlu_confidence_threshold = 0.7
      voice_settings = {
        engine   = "standard"
        voice_id = "Kevin"
      }
      intents = [
        {
          name = "Sales"
          sample_utterances = [
            {
              utterance = "sales"
            }
          ]
          dialog_code_hook = {
            enabled = false
          }
          fulfillment_code_hook = {
            enabled = false
          }
        },
        {
          name        = "FallbackIntent"
          description = "Default intent when no other intent matches"
          dialog_code_hook = {
            enabled = false
          }
          fulfillment_code_hook = {
            enabled = false
          }
          parent_intent_signature = "AMAZON.FallbackIntent"
        }
      ]
    }
  ]
}

3. Run terraform plan (completes successfully)
4. Run terraform apply (fails with above error)

Steps to Reproduce

Important Factoids

• The error occurs consistently across multiple provider versions (1.17.0, 1.19.0)
• The issue manifests both during initial creation and updates of the bot
• terraform plan completes successfully, suggesting the configuration is valid
• The error appears to be related to state handling within the provider, specifically around the bot_locales attribute
• The error occurs in both CI/CD pipeline and is expected to reproduce locally

Possible Impact

This issue prevents the creation and management of Lex bots through Terraform, requiring manual intervention or alternative approaches.
