Terraform Configuration Files

resource "aws_bedrockagent_agent" "test" {
  agent_name                  = "test"
  agent_resource_role_arn     = aws_iam_role.test.arn
  prepare_agent               = true
  foundation_model            = "anthropic.claude-3-sonnet-20240229-v1:0"
  idle_session_ttl_in_seconds = 60

  prompt_override_configuration {
    prompt_configurations = [
      {
        base_prompt_template = file("${path.module}/prompt_templates/post_processing.json")
        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

• terraform apply with the includes resource definition. It will succeed to create the agent if the prompt_override_configuration is left out.

@kmcduffee-verisk Looking at your error you created the agent without any prompts then updated it to add one?

[kmcduffee-verisk]

@drewtul It seems to happen either way.

[drewtul]

@kmcduffee-verisk Does it happen on the first apply or the second, I can provoke an error by providing some overrides but not all and I've got a fix for this, but I'm not getting the same error as you.

[drewtul]

@kmcduffee-verisk I can reproduce your error, but only by having a block:

resource "aws_bedrockagent_agent" "test" {
  agent_name                  = "test"
  agent_resource_role_arn     = aws_iam_role.test.arn
  prepare_agent               = true
  foundation_model            = "anthropic.claude-3-sonnet-20240229-v1:0"
  idle_session_ttl_in_seconds = 60
  instruction = "Something here"
  prompt_override_configuration {
  }
}

Can you double check you don't have any typo on prompt_configurations in your configuration?

[kmcduffee-verisk]

@drewtul Thanks for digging in! Indeed, the issue appears to have been with my prompt template file. In the AWS UI, where the JSON worked fine as-is, there was a newline after the first quote of the content block. Once I brought the text back up to the quote, it all worked.

I did run into an issue related to #37168 though. It appears that if you do not provide prompt configurations for every prompt (orchestration, pre, knowledge, post), you will get the error noted there. I was only able to get bast that issue doing the following, basically blanking out the other options (since my agent does not use them):

  prompt_override_configuration {
    prompt_configurations = [
      {
        base_prompt_template = "{\"anthropic_version\":\"bedrock-2023-05-31\",\"system\":\"\",\"messages\":[{\"role\":\"user\",\"content\":\"\"}]}"
        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         = "DISABLED"
        prompt_type          = "PRE_PROCESSING"
      },
      {
        base_prompt_template = "{\"anthropic_version\":\"bedrock-2023-05-31\",\"system\":\"\",\"messages\":[{\"role\":\"user\",\"content\":\"\"}]}"
        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         = "DISABLED"
        prompt_type          = "ORCHESTRATION"
      },
      {
        base_prompt_template = "You are not a knowledge base assistant."
        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         = "DISABLED"
        prompt_type          = "KNOWLEDGE_BASE_RESPONSE_GENERATION"
      },
      {

        inference_configuration = [

            top_k          = 250
            top_p          = 1

        ]

        prompt_state         = "ENABLED"
        prompt_type          = "POST_PROCESSING"
      }
    ]

@kmcduffee-verisk I did encounter the error from #37168 and I've raised a PR to fix that issue with some further tests covering adding/removing and partial prompt configuration.
