Terraform：S3触发代码失败，状态代码：400

问题描述

在terraform中，尝试将S3存储桶作为我的lambda的触发器并提供权限。对于此用例，创建S3资源并尝试在触发逻辑中引用该lambda函数。但是，当我引用代码失败时，出现以下错误。请帮助我解决此问题。

resource "aws_lambda_function" "test_lambda" {
  filename      = "output/welcome.zip"
  function_name = var.function_name
  role          = var.role_name
  handler       = var.handler_name
  runtime       = var.run_time

  bucket = aws_s3_bucket.bucket.id
  lambda_function {
    lambda_function_arn = aws_lambda_function.test_lambda.arn
    events              = ["s3:ObjectCreated:*"]
    filter_prefix       = "file-prefix"
    filter_suffix       = "file-extension"
}
}




resource "aws_lambda_permission" "test" {
  statement_id  = "AllowS3Invoke"
  action        = "lambda:InvokeFunction"
  function_name = aws_lambda_function.test_lambda.function_name
  principal = "s3.amazonaws.com"
  source_arn = "arn:aws:s3:::aws_s3_bucket.bucket.id"
}

错误消息：

Error: Error putting S3 notification configuration: InvalidArgument: Unable to validate the following destination configurations
        status code: 400,request id: 8D16EE1EF8FC0E63,host id: PlzqurwmHo3hDJdr0nUhOGuJKnghOBCtMImZ+8fEFX3JPjKV2M47UZuJ5Z26FalKxmoF1Xl8lag=

解决方法

您在source_arn中的aws_lambda_permission不正确。应该是：

source_arn = aws_s3_bucket.bucket.arn

目前，您的source_arn实际上是字符串“ arn：aws：s3 ::: aws_s3_bucket.bucket.id”，这是不正确的。
