我开始尝试用node和puppeteer写一个lambda函数。我使用的是无服务器框架
我一直在努力遵循 https:/codissimo.sinumo.tech20191227serverless-puppeteer-with-aws-lambda-layers-and-node-js。 以利用提供的chrome在 https:/github.comshelfiochrome-aws-lambda-layer。 . 我的函数在本机上工作得很正常。
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
当我运行时:

我怎样才能解决这个问题？
编辑：我的Yaml文件包含：当我运行时：如何解决这个问题？
现在得到的是：
所以我想以后我会用一个工具，比如说 https:/www.convertjson.comyaml-to-json.htm. 谢谢你，我改成了 我改成了:
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？
你的层ARN里有个空格。
你的配置在YAML:
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中看起来是这样的 -- 在这里变得更加明显。
{
"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"
}
]
}
}
