Question

我开始尝试用node和puppeteer编写lambda函数。我正在使用无服务器框架

我一直在尝试遵循https://codissimo.sinumo.tech/2019/12/27/serverless-puppeteer-with-aws-lambda-layers-and-node-js/来利用https://github.com/shelfio/chrome-aws-lambda-layer处的预置chrome。我的功能在本地正常工作。

我的Yaml文件包含：

provider:
  name: aws
  runtime: nodejs12.x
  region: us-east-1
  # here we put the layers we want to use
  layers:
    # Google Chrome for AWS Lambda as a layer
    # Make sure you use the latest version depending on the region
    # https://github.com/shelfio/chrome-aws-lambda-layer
    - arn:us-east-1: arn:aws:lambda:us-east-1:764866452798:layer:chrome-aws-lambda:10

当我跑步时：

$ serverless deploy

我该如何解决？

编辑：

现在得到：

所以我想将来我会使用类似https://www.convertjson.com/yaml-to-json.htm的工具。谢谢。我改为：

layers:
  - arn:us-east-1:arn:aws:lambda:us-east-1:764866452798:layer:chrome-aws-lambda:10

现在我看到了：

 An error occurred: MainLambdaFunction - 1 validation error detected: Value '[arn:us-east-1:arn:aws:lambda:us-east-1:764866452798:layer:chrome-aws-lambda:10]' at 'layers' failed to satisfy constraint: Member must satisfy constraint: [Member must have length less than or equal to 140, Member must have length greater than or equal to 1, Member must satisfy regular expression pattern: (arn:[a-zA-Z0-9-]+:lambda:[a-zA-Z0-9-]+:\d{12}:layer:[a-zA-Z0-9-_]+:[0-9]+)|(arn:[a-zA-Z0-9-]+:lambda:::awslayer:[a-zA-Z0-9-_]+)] (Service: AWSLambdaInternal; Status Code: 400; Error Code: ValidationException; Request ID: a5fae73b-67b5-4910-8020-c283673e55f2).

有什么想法吗？

ARN层中有一个空格。

您在YAML中的配置：

provider:
  name: aws
  runtime: nodejs12.x
  region: us-east-1
  # here we put the layers we want to use
  layers:
    # Google Chrome for AWS Lambda as a layer
    # Make sure you use the latest version depending on the region
    # https://github.com/shelfio/chrome-aws-lambda-layer
    - arn:us-east-1: arn:aws:lambda:us-east-1:764866452798:layer:chrome-aws-lambda:10

...在JSON中看起来像这样-变得更加明显：

{
  "provider": {
    "name": "aws",
    "runtime": "nodejs12.x",
    "region": "us-east-1",
    "layers": [
      {
        "arn:us-east-1": "arn:aws:lambda:us-east-1:764866452798:layer:chrome-aws-lambda:10"
      }
    ]
  }
}

Lambda：属性图层的值必须为字符串列表类型
