[mervintankw]

Terraform Core Version

0.13.7

AWS Provider Version

5.76.0

Affected Resource(s)

• aws_bedrockagent_agent

Expected Behavior

The provider should accept the prompt_override_configuration block and create the Bedrock agent with the specified prompt configurations.

Actual Behavior

The provider produces an invalid plan with a type mismatch between the configuration and the planned value.

Terraform Configuration Files

resource "aws_bedrockagent_agent" "agent" {
  prompt_override_configuration {
    prompt_configurations = [{
      base_prompt_template = "test"
      inference_configuration = [{
        max_length     = 2048
        stop_sequences = ["\n\nHuman:"]
        temperature    = 0
        top_k         = 250
        top_p         = 1
      }]
      parser_mode          = "DEFAULT"
      prompt_creation_mode = "OVERRIDDEN"
      prompt_state        = "ENABLED"
      prompt_type         = "POST_PROCESSING"
    }]
  }
}

Steps to Reproduce

1. Create a new directory and initialize Terraform:

mkdir bedrock-agent-test
cd bedrock-agent-test
terraform init

2. Create a main.tf file with the following minimal configuration:

provider "aws" {
  region = "us-east-1"  # or your preferred region
}

resource "aws_iam_role" "agent_role" {
  name = "bedrock-agent-test-role"
  
  assume_role_policy = jsonencode({
    Version = "2012-10-17"
    Statement = [
      {
        Action = "sts:AssumeRole"
        Effect = "Allow"
        Principal = {
          Service = "bedrock.amazonaws.com"
        }
      }
    ]
  })
}

resource "aws_bedrockagent_agent" "agent" {
  agent_name              = "test-agent"
  agent_resource_role_arn = aws_iam_role.agent_role.arn
  instruction            = "You are a helpful assistant"
  foundation_model      = "anthropic.claude-v2"

  prompt_override_configuration {
    prompt_configurations = [{
      base_prompt_template = "test"
      inference_configuration = [{
        max_length     = 2048
        stop_sequences = ["\n\nHuman:"]
        temperature    = 0
        top_k         = 250
        top_p         = 1
      }]
      parser_mode          = "DEFAULT"
      prompt_creation_mode = "OVERRIDDEN"
      prompt_state        = "ENABLED"
      prompt_type         = "POST_PROCESSING"
    }]
  }
}

3. Run terraform commands:

terraform init
terraform plan

4. Observe the error:
