【问题描述】：

我正在尝试创建一个触发器，以便每次在我的发电机表 filenames 中创建一个新条目时，都会触发 lambda 函数 trigger_lambda_function。我跟着这个：https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/lambda_event_source_mapping

resource "aws_dynamodb_table" "filenames" 
  name           = local.dynamodb_table_filenames
  billing_mode   = "PROVISIONED"
  read_capacity  = 1000
  write_capacity = 1000
  hash_key       = "filename"

  #range_key      = ""

  attribute 
    name = "filename"
    type = "S"
  

  tags = var.tags



resource "aws_lambda_event_source_mapping" "allow_dynamodb_table_to_trigger_lambda" 
  event_source_arn  = aws_dynamodb_table.filenames.stream_arn
  function_name     = aws_lambda_function.trigger_stepfunction_lambda.arn
  starting_position = "LATEST"

目前，我收到一个错误：

│ Error: error creating Lambda Event Source Mapping (): InvalidParameterValueException: Unrecognized event source.
│ 
│   RespMetadata: 
│     StatusCode: 400,
│     RequestID: "5ae68da6-3f6d-4adb-b104-72ae584dbca7"
│   ,
│   Message_: "Unrecognized event source.",
│   Type: "User"
│ 
│ 
│   with module.ingest_system["alpegatm"].aws_lambda_event_source_mapping.allow_dynamodb_table_to_trigger_lambda,
│   on ../../modules/ingest_system/dynamo.tf line 39, in resource "aws_lambda_event_source_mapping" "allow_dynamodb_table_to_trigger_lambda":
│   39: resource "aws_lambda_event_source_mapping" "allow_dynamodb_table_to_trigger_lambda" 

我该如何解决这个问题？我使用的event_source_arn 有什么问题？

【参考方案1】：

我认为您需要为发电机表打开流式传输。
