从VPC内部访问VPC外部的AWS资源-无服务器框架

我正在尝试从VPC内的lambda函数访问VPC外部的运动流.当前，当执行写入运动流的代码时，它将挂起，然后超时.当我从VPC中取出lambda时，写入流的代码可以正常工作.但是我需要访问VPC中的资源，然后写入流中.有人知道怎么修这个东西吗?

I am trying to access a kinesis stream outside a VPC from a lambda function inside a VPC. Currently when the code to write to the kinesis stream is executed it will hang and then timeout. When I take the lambda out of the VPC the code to write to the stream works fine. But I need to access a resource within the VPC and then write to the stream. Anyone know how to fix this?

这是我在VPC中的功能

Here is my function that is in the VPC

functions:
  handleChanges:
    handler: functions/handlers.handleChanges
    timeout: 10
    package:
      include:
        - functions/utils/**
    events:
      - http:
          method: POST
          path: "/"
          integration: lambda
    vpc:
      securityGroupIds:
        - ${file(./private.yml):variables.securityGroup}
      subnetIds:
        - ${file(./private.yml):variables.subnetID}

这是我的政策

iamRoleStatements:
  - Effect: "Allow"
    Action:
      - "kinesis:PutRecord"
      - "kinesis:GetRecords"
      - "kinesis:GetShardIterator"
      - "kinesis:DescribeStream"
      - "kinesis:ListStreams"
    Resource:
      Fn::GetAtt:
        - KinesisStream
        - Arn
  - Effect: "Allow"
    Action:
      - "cognito-idp:AdminGetUser"
    Resource: "*"
  - Effect: "Allow"
    Action:
      - "logs:CreateLogGroup"
      - "logs:CreateLogStream"
      - "logs:PutLogEvents"
      - "ec2:CreateNetworkInterface"
      - "ec2:DescribeNetworkInterfaces"
      - "ec2:DeleteNetworkInterface"
    Resource: "*"

最后是我的运动学流资源

And finally here is my kinesis stream resource

KinesisStream:
  Type: AWS::Kinesis::Stream
  Properties:
    Name: ${self:provider.environment.STREAM_NAME}
    ShardCount: 1
