[Bug]: `aws_lambda_function` waits on ResourceConflictException for existing function name

[jar-b]

Terraform Core Version

v1.3.7

AWS Provider Version

v4.52.0

Affected Resource(s)

• aws_lambda_function

Expected Behavior

The create operation should fail as soon as an error indicating the function name already exists is returned. For example,

ResourceConflictException: Function already exist: hello_lambda

Actual Behavior

The create operation continues until eventually timing out.

Terraform Configuration Files

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 4.0"
    }
  }
}

provider "aws" {}

data "aws_iam_policy_document" "trust" {
  statement {
    effect = "Allow"
    principals {
      identifiers = ["lambda.amazonaws.com"]
      type        = "Service"
    }
    actions = ["sts:AssumeRole"]
  }
}

resource "aws_iam_role" "iam_for_lambda" {
  name               = "iam_for_lambda"
  assume_role_policy = data.aws_iam_policy_document.trust.json
}

resource "aws_lambda_function" "test" {
  function_name = "hello_lambda" # this name already exists

  filename = "java11-hello-example.zip"
  handler  = "example.Hello::handleRequest"
  role     = aws_iam_role.iam_for_lambda.arn
  runtime  = "java11"
}

Steps to Reproduce

1. Create a function in the console or separate configuration from above.
2. Attempt to use the same name in the configuration above, run terraform apply.
3. Observe waiting behavior and eventual timeout.
